If you continue on the path of building your own tools, the command
"ldconfig -p" is your friend.  This command will show you all the
libraries known and cached.  If you installed a library from source and
don't see it listed, you may need to run "ldconfig" as root to update
the cache.  I've mostly seen this out-of-date cache problem on
Fedora/CentOS systems but it can't hurt to check.
