Stop the postmaster so that createdb fails for both logins, and compare
the error messages --- are they pointing to the same socket file? I
suspect JD's diagnosis is right: you probably have got two postgres
installations (or parts of two at least) with different ideas of where
the communication socket should be.

"man chkconfig" might help you with this one. Linux systems are not
normally made to auto-start services unless they're very specifically
requested.
By and large, it's a lot less painful to use a preconfigured package
than to try to install from source.
