Ruby on Rails - Error installing bdb. Failed to build gem native extension

Question

When running gem install bdb I get the following error:

Error installing bdb:
ERROR: Failed to build gem native extension.

Anyone know where I can find the bdb library for Mac OS X?

Full error:

Did you see the instructions on the bdb page?

As a Gem

At the moment this library is not available on RubyForge. To install it as a gem, do the following:

[sudo] gem install bdb

For Berkeley DB v4.7 installed from MacPorts do the following:

[sudo] env ARCHFLAGS="-arch i386" gem install bdb This assumes you're on OS X and BerkeleyDB wasn't compiled as a universal binary.

So it looks like you need to install berkeley db via macports/brew to get the Gem to install.
