Hi Jan,

there were still some small isues with the patch format, I've attached
a version of your patch that has the expected format.

Note that I also changed it to only check the canonical names instead of
testing the passed in one and the one readlink was called on.  This
should be enough I think, but please test that it still works for you.

Thanks for tracking this down!

Subject: [PATCH] libhandle: fix instalation for symlinked /usr

Canonicalize the pathnames for PKG_LIB_DIR and PKG_ROOT_LIB_DIR before
checking if they are the same.  This is required for Fedora which doesn't
have a separate /usr/lib directory anymore.
