If you've got Ruby from the one-click installer, you should be able to 
install the gems for the PostgreSQL interface. If you're behind a 
firewall, you might need to have IT help you, but essentially, all you 
need to do is open up the RubyGems command line gem installer that comes 
with the one-click installer and install the gem(s).

There are two Ruby/PostgreSQL interface gems, one with some C language 
code and one that is pure Ruby. Your problem indicates that you tried 
the one with C code. I don't have a Windows system with one-click handy, 
but my recollection is that the gem for the C-language version is 
pre-compiled for Windows.

I have never used either version, so I can't comment on whether the pure 
Ruby or the C-language version is "better" by any definition of the 
word. But one way or another, if you use the one-click installer, you 
should be able to get up and running via RubyGems without PostgreSQL source.
