[Bioperl-l] a thought on Bio::Root::Build

[Mark A. Jensen]

Is it a reasonable convenience for the user who has run ./Build.PL
with a non-default set of install directories to ask CPAN::Shell
to use those directories when installing prerequisites (unless 
the user's MyConfig.pm is saying something else)? The following
does this in a prob not very robust way (but it seems to work):
