Not so clean.

tried to update cpan
perl -MCPAN -e ‘install Bundle::CPAN’

catastrophic errors all over the place. I thought it was just the Scalar List Utils error from a while ago, but Perl is hoaked - feeds you back pages of

/usr/lib/perl/5.8/CORE/perl.h:420:24: error: sys/types.h: No such file or directory

until you run:

apt-get install libc6-dev


Or apparently you need to install the build-essential package.

Ok, so you still need to install Scalar List Utils (because the XS version isn’t included)
Then install Compress-Zlib, and to do that, manually install all the prereqs.

PITA.
