Looking for most efficient way to verify specifically installed libraries

[vpic]

Hello,
I'm looking to check the current installed libraries of my system against a known pre-requisite list. For example, I'm finally getting time to try out e17 Window Manager and the kind folks on the Enlightenment dev team have provided this list (http://wiki.enlightenment.org/index.php/E17_User_Guide/Installing_from_Source_Repository) of tools to make sure I have.

I have been using the following algorithm (manually, btw):
1. Check /usr/ports and search for string of library_name using make search name=<library_name>

2. Trying to see if library is already installed using pkg_add -r <library_name> and checking for either install or package already installed message

3. Various combinations of pkg_info or pkg_version, but either not getting specific info for <library_name> or getting a message that <libarary_name> doesn't exist (probably because I'm not specifying the version number).

4. Going to the port master index and string-searching for the <library_name> and then following hyperlinks to read the appropriate descriptions and, essentially, guessing.

I am learning a lot about a lot of commands this way, but I'd just assume figure out something a little more efficient and then script it

Any suggestions? Anything as simple as looping the list referenced above into a FreeBSD equivalent of rpm -qa | grep <pkg_name>?

Thanks in advance,
vPic

uh, something like:

pkg_info -Ex <library-name> || pkg_add -r <library-name>

?

Yeah, just like that Thanks for the quick reply.

This may be somewhat off topic, but e17 is in the ports tree, although it's not based on the latest snapshot.

Using ldconfig is the most direct, low level, sure fire way of checking I think.

ldconfig -r

combined with an awk/sh/python/etc. recipe of your imagination.
