While emerging unison-2.13.0 I got the error while compiling lablgtk. It seems like the problem comes from having USE="opengl" flag enabled. # emerge -av unison These are the packages that I would merge, in order: Calculating dependencies ...done!

Created attachment 67962 [details] lablgtk-2.4.0/config.log emerge said: !!! Please attach the config.log to your bug report: !!! /var/tmp/portage/lablgtk-2.4.0/work/lablgtk-2.4.0/config.log So, the file is attached.
You probably have a messed up gtkgl installation (try to find gtkgl-2.0.pc somewhere in /usr, it should be in /usr/lib/pkgconfig). Try with the latest gtkglarea ebuild and it should work fine.
You're probably right. Trying newer versions is always a good habit :) Thanks for the suggestion - I'll try it if I hit the same problem again.
