[Tom Allison]

Well this is a sticky spot.

None of the modules/packages/gems/.... work and here's more.
And now I will have three different installations of postgres running on

How is it that Perl has a DBI that is largely libpq independent and Ruby 
is largely .. not.  Sign of maturity of the language?
