Ah, cool. One more question:

So, for point 2, one would need Perl 5.8.3 + a newer Test::More and
IPC::Run, or a newer Perl. I've toyed around with cpanminus:
apt-get install cpanminus
and it successfully build (in a local path because I was not root) the
latest Test::More and IPC::Run. I'm not sure if this would be enough to
run the MSVC build scripts, tho.
So, is the goal you are trying to achive here to be able to say "You need
Perl 5.8.3; plus Module XYZ in vABC if you want point 2, otherwise skip
this step" instead of saying "You need Perl 5.10.1?"?
In that case it might be also possible to write instructions on how to
obtain and use these modules, or how to just use a newer Perl in a temp.
