APM: Configuring Perl

[Montgomery Conner]

If you're in the mood for a good long read there's an INSTALL file
distributed with the Perl source. It has very detailed instructions for all
of the various build options.

But everytime I start to read that document my eyes glaze over and I end up
just using the defaults and the auto-discovery provided by Configure...
which always seems to just work (with the sole exception being an
installation I attempted on an ARM5 Sheeva SoC system running Ubuntu...
which required a little TLC ;-) ).
