Re: Error trying to install Ruby postgres gems on OS/X

So I installed the postgres-pg library, which if I understand
correctly is a Ruby implementation of the adapter (as opposed to
native code that has to be built) and that's working fine..

From what I've read, this adapter is much slower but probably fine for
non-production use (I'm just learning for now)..

However, if anyone has any ideas how to install the native adapter, lemme know!
