Description Adam Feldman gentoo-dev

winegcc attempts to guess the libdir which doesn't work with the prefixed installation directories.  The default symlinks for plain old wine's libdir work with winegcc's autodetection code, however no other symlinks work (ie for /usr/bin/winegcc-2.2 or /usr/bin/winegcc-vanilla, etc).

The only consumer that would have really caused a problem for this was www-plugins/pipelight (since we'd be using the -staging variant), but since that was recently removed from the tree, I'm adding this as a reminder to fix this bug, and won't be holding up unmasking of the slotted packaging based on this bug report.

The issue is in the get_lib_dir function.  I haven't come up with the best way to resolve it yet.

NP, I've had a dive into this issue... However I can't seem to reproduce it. The variant winegcc-* wrappers appears to work on my system.

I used the attached patch to verify the operation of the get_lib_dir() function.
