Perl is downgraded

J

I had perl 5.14.1 installed. After installing apache with pkg_add perl is downgraded to 5.10 without notice. Same happened earlier when I installed Midnight Commander from ports. Are both versions of perl on my machine or is the upper version overwritten by lower version?

How can I prevent perl from downgrading in future?
 
In addition: pkg_info shows both versions of perl available. But perl -v shows perl 5.10.

/etc/make.conf has 5.10 entry
 
Code: 
 portmaster -i -d -B /var/db/pkg/apache... /var/db/pkg/mc-..
*Almost* without fail, you would answer NO to any unwanted perl install. However, pkg_add is not under such user control at all times.
Code: 
cd /var/db/pkg
ls -lac | grep perl
should show which perl(s) are installed. Maybe deinstall the perl you do not wish to have installed ?
(Short answer anyway.)
 
portmaster command did not work. But second command shows two versions of perl installed. But system uses older perl. I tried pkg_delete for both versions of perl. Due to different dependencies, unable to delete either. How to make all dependencies use the latest version?
 
See the several entries about Perl in /usr/ports/UPDATING, most of which refer back to the 20100715 entry. It might help to force-delete the newer version first with -f to pkg_delete(1).

perl-5.12 is the standard version right now.
 
@joe5000: this might be a symptom of mixing Ports with packages, at least in the case of Apache web server. As for building Ports, try putting this in /etc/make.conf
Code: 
PERL_VERSION=5.14.1

If that doesn't work, it might (haven't tested it) be possible to have both working versions of Perl installed. Your scripts that need the 5.14 branch would need to point to its interpreter, rather than the generic (symlinked) /usr/bin/perl.
 
Code: 
 pkg_delete -f /var/db/pkg/perl ...
then maybe run portmaster on any program that does not work because it was deleted. (Will be shown in the output from that command, which ones... the contents of +REQUIRED_BY

It looks like FreeBSD packages install whatever perl version they like, ignoring existing higher version.

I noticed that two versions of perl installed on my machine. Packages install the perl they want under /usr/local/bin/ directory and create /usr/bin/perl and /usr/local/bin/perl5 symbolic links.

They say if I insert
Code: 
PERL_VERSION=5.14.1
in /etc/make.conf, then packages/ports will not dare to change it. (not tested)

Ok, now, I get 5.14 version with perl -v command. I tried to run cpan to install some modules. There I had a new problem to report to Houston. Module installation gets stuck during testing at t/INSTALL_BASE.t, can exit only with ctrl-c.

This fellow had the same problem: http://www.nntp.perl.org/group/perl.makemaker/2011/09/msg3276.html
This fellow also mentions some regex error: http://www.perlmonks.org/?node_id=918598

I chatted in perl irc about it. Perl guys suspect some bug with FreeBSD.

FYI: I run FreeBSD 8.2 under vmware player 3.1.

May be better to not install Perl modules on FreeBSD that way. What's the module? Is it not in Ports already?

You can search like:
Code: 
%cd /usr/ports && make search display=path name='p5.*graph'
Path:	/usr/ports/biology/p5-Bio-Graphics

Path:	/usr/ports/databases/p5-GraphViz-DBI

Path:	/usr/ports/devel/p5-B-Graph

Path:	/usr/ports/graphics/p5-Acme-Steganography-Image-Png

Path:	/usr/ports/graphics/p5-Chart-Graph

Path:	/usr/ports/graphics/p5-Chart-PNGgraph

Path:	/usr/ports/graphics/p5-GD-Graph

...

Or you can search on Freshports.
 
I've just encountered this problem. Setting
Code: 
PERL_VERSION=5.14.1
in /etc/make.conf didn't help, but setting
Code: 
PERL_PORT=perl5.14
in /etc/make.conf fixed the problem for me.

There's probably many good reasons not setting PERL_PORT in /etc/make.conf (otherwise someone would have already suggested doing this), but I'm on a tight deadline and it fixed my immediate problem... �e
