By personal experience, I believe that this is over-simplifying a bit.
Ubuntu/Debian packages are nice, and they "just work".
But these packages work by putting (very clever) links all over the place, and I wish good 
luck to someone wanting to combine this with, for example, another perl and a mod_perl 
installed from source, while keeping the same Apache.
(E.g. if it needs changing the LoadModule line in Apache, then of course you cannot run 
this concurrently with the normal version.)
And trying to install a CPAN package over that, to a directory library that is not the 
default one, is a real pain.  At least the last time I tried.

Admittedly, I am not the ultimate perl/mod_perl expert, and in the end I will defer to the 
real experts.  But I believe that the OP is not a real expert either, and for now I'll 
stick to my earlier recommendation.
