RPM vs. Source

Hello,

I've successfully set-up Postgres 7.2 via RPM under Mandrake 8.0.  I've also set it up perfectly compiling the source.
However,
there is one difference I need to resolve:

When I install via RPM, the script /etc/rc.d/init.d/postgresql gets installed and that enables me to start postgres as
aservice. 
However, I also want to install postgres from source and run it as a service in other Linux distros.

How would I do this?


Thanks!
