One small bit to add here, and it may not be related, but I have  
noticed a very interesting error popping up with a majority of the  
CPAN Testers cases using CPANPLUS (example here: http://www.nntp.perl.org/group/perl.cpan.testers/2009/01/msg3113770.html) 
:

- ERROR: IO::String is not installed

Note that the CPAN module is being called from within CPANPLUS (likely  
via Bio::Root::Build), I think causing a permissions issue.  Not a  
huge worry (the tests are marked UNKNOWN) but I'm wondering if we  
should bypass automatic installation of required modules if called  
from within the CPAN/CPANPLUS shell for this reason.  Either that or  
try to determine whether CPAN or CPANPLUS is being used and then use  
the correct shell for retrieving and installing modules.
