libdl in glibc 2.3.6-r5 /usr/lib/libdl.so is a relative symlink to /lib/libdl.so.2 - i.e. ls -l /usr/lib/libdl.so gives libdl.so -> ../../lib/libdl.so.2 The use of a relative symlink breaks the library in instances where /usr is located elsewhere (e.g. /export/usr) and is symlinked into place (e.g. ln -s /export/usr /usr). This break manifests as an inability to link against libdl when building ebuilds such as gawk, baselayout, etc, causing failed ebuilds. I fail to see any Good Reason for the use of relative symlink in this instance so I'm submitting it as a bug! If you need further information then you are very welcome to contact me
Don't move /usr via symlinks. *** This bug has been marked as a duplicate of 112413 ***
