===>  Script "configure" failed unexpectedly.
Please report the problem to [maintainer] and attach the
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/local/sbin/pkg-static info -g -Ea).

security/botan is installed. Is it a missing library? Thank you.
According to devel/monotone/Makefile you should have installed security/botan110.
Thank you for replying. I will double-check when I get home. However my memory is that portmaster pulled in security/botan110 when I proposed to install monotone. So I made a typo in the first post.
Where does ./configure search for botan1.10, under /usr/local/include I suppose? Or is this where devel/pkgconf comes in? I see the process found botan-1.10.pc, is that relevant?
Can anyone reproduce this?

Thank you.
Well, you're using FreeBSD 11/amd64 so I guessed that could be a problem but according to portsmon, it builds fine on 11.

Check out that you're using the default configuration options for security/botan110 and you don't have something out of place in your /etc/make.conf
Well, now devel/monotone gets past the configure stage. security/botan110 needed a rebuild due to the devel/boost upgrade to 1.62 I think. Perhaps that is why?
Anyway, now devel/monotone fails to build with:

Perhaps it is time for a bug report.
I decided to newly install FreeBSD 11 from svn sources onto a new disk, as the current HDD was getting to be 5+ years old. Plus install all ports anew from source. So now devel/monotone builds fine from ports.
If only the issue of www/firefox crashing with "bus error" (according to zsh/tcsh) or unaligned memory access (according to shells/fish) had not migrated over to the new drive....
