The auto-config is pretty good now. I like to put a new version
of Perl in a dir, '/usr/local/perl-5.8.5', then I have a script
which configs CPAN and installs all the modules that I need/want.
I run some tests, if the new Perl install is working okay, I have
a symlink /usr/local/perl which points to the version I want to use.
If something is wrong I can always point /usr/local/perl back to the
older install. This works really well, for me at least, at work. I
can have the other developers test production code in without affecting
production. As far as compiling, I let Perl config,
sh Configure -de -Dprefix=/usr/local/perl-5.8.x
..not that you care how I install Perl, just thought I would share. :-)

I'm pretty sure that perl will include other 5.* in the
/usr/local/lib/perl5/site/ dir.
