Thanks very much. I actually got there myself having noted the word PREFIX
going by in the CPAN config sequence but I probably should read that perldoc as
it was really a flying blind type thing.

I never thought of that. As I built a new perl anyway (5.8) I'm prpbably locked
out of using mod_perl now anyway.
BTW, the system does seem to use the postgres installation it had. There's a
cobalt database. I didn't fancy trying to upgrade it since I have no idea what
the system is using it for.
