AIUI, the Perl bindings are meant to install into the location where
Perl is installed--regardless of the value specified for prefix.  On
some systems (i.e. mine), the user may choose to install Myth to
/usr/local, but Perl's @INC may not include /usr/local/lib/perl5.  So,
if the bindings were installed into /usr/local, Perl would be unable to
find them unless I were to recompile my Perl to add the dir to @INC,
export a PERL5LIB env var, call perl with -I/usr/local/lib/perl5, modify
scripts which use Myth Perl bindings to include "use lib ..." or BEGIN {
push @INC,...}, ...--basically things that I don't want to do.

By putting Perl modules into the Perl modules directory defined for the
system regardless of the configure prefix, Perl can always find them.  :)
