I'm trying to install the Postgres gem on OS/X but getting errors no
matter what I try.. In theory, it should be as simple as "gem install
postgres", correct? Here's what I get:
>sudo gem install postgres
Building native extensions. This could take a while...
ERROR: Error installing postgres:
ERROR: Failed to build gem native extension.

=========== WARNING ===========
You are building this extension on OS X without setting the
ARCHFLAGS environment variable, and PostgreSQL does not appear
to have been built as a universal binary. If you are seeing this
message, that means that the build will probably fail.
Try setting the environment variable ARCHFLAGS
to '-arch i386' before building.
For example:
(in bash) $ export ARCHFLAGS='-arch i386'
(in tcsh) $ setenv ARCHFLAGS '-arch i386'
Then try building again.

I have Postgres 9.0 installed at /Library/PostgreSQL/9.0. Any ideas?
