Another way to avoid them, at least in perl, is to perlc all of your
utilities at build-time.  A much better solution!  This points out a
huge problem with linux distros (and many open source apps) that they
think they're doing you a favor by including some version of whatever.
 It just creates confusion and a lot of replication in /usr/local.
