Use single library path.

There can be several directories, where libs are being searched for.
That behavior can be either hardcoded in the specific program, or
defined in /etc/ld.so.conf. To keep things simple, I'd just use
lib/lib64 (libe is a symlink to lib64) well-known location for the
shared libs.
