Ruby pg Gem

[Malmoth]

The most recent Ruby gem for PostgreSQL access is pg.

However, since the required PostgreSQL headers do not exist on the server, gem can't build the native extension for pg.

Is it possible to install PostgreSQL headers?

Okay, I've just installed the pg gem from the root console. It is should now be available for use in your applications. Let me know if you have any difficulties.
