Mac OS X X11 Behaviour and DarwinPorts

I seem to have done something wrong or have misunderstood how to configure Mac OS X 10.4.8 to use DarwinPorts. Although ~/.profile exists and .../xinit/xinitrc includes "source ~./ profile", only the first xterm window opened will have "/opt/local/ bin:/opt/local/sbin:" set in its environment. When I open subsequent xterm windows, I need to explicitly enter the command "source .profile" to include the path to the DarwinPorts X11 applications. On my original PowerBook G4, I had set my default shell to tcsh. I failed to do this when I acquired my PowerMac G5. The default shell is bash. Do I need to change my default shell?
