Hello. Upon eselect-openg-1.3.1-r2 merge the following output is produced by portage: >>> Installing (1 of 1) app-admin/eselect-opengl-1.3.1-r2::gentoo * checking 1 files for package collisions >>> Merging app-admin/eselect-opengl-1.3.1-r2 to / --- /usr/ --- /usr/share/ --- /usr/share/eselect/ --- /usr/share/eselect/modules/ >>> /usr/share/eselect/modules/opengl.eselect >>> Safely unmerging already-installed instance...

Note those "find: `//usr/lib*/opengl': No such file or directory" messages. Please fix. Reproducible: Always
Why is this a problem?
(In reply to Jeroen Roovers from comment #1) > Why is this a problem? Because this is an error message from `find`. It shouldn't be in the portage output.
It's because the glob doesn't expand if the directory doesn't exist. But even if it does this is going to give you an error. If /usr/lib is a symlink to /usr/lib64 find will end up passing two paths to rmdir, and obviously the second will fail. I don't think -xtype is portable. I can't remember if we require gnu find. Something like this should work: find /usr/lib*/ -name opengl -xtype l -delete find /usr/lib*/ -depth -name opengl -type d -empty -exec rm -dfv {} +

It will find random 'opengl' symlinks and directories throughout /usr/lib*.
+ 22 Jan 2015; Michał Górny <mgorny@gentoo.org> eselect-opengl-1.3.1-r2.ebuild: + Avoid error messages when /usr/lib*/opengl does not exist, bug #537224. Used the easy way of path_exists.
