What I find a problem with CPAN modules is that it is not clear what
these modules in their turn depend on (BioPerl needs module A, A needs
B). It is also sometimes hard to find which module a certain module is
located (finding IO::Scalar in IO-stringy-1.211 is not straightforward).

I do think that we should not depend on external packages like we do now
with 'expat' which is needed for one of the XML modules. There are
companies where only the installation of CPAN modules is allowed.

P.S. I know about CPAN.pm, but had some bad experiences with it :(
