Database installation query (PostgreSQL 7.4)

Hi,

How can I install PostgreSQL 7.4 in a directory other than the --prefix
directory without having to recompile the code. Note that, I have to
make a tar file of the installable files and have to install it on
different machines (which may have different paths).

When I tried this on one of the machines, I got following error:

bash-2.03$ /export/home/postgres/bin/initdb -D
/export/home/postgres/data -L /export/home/postgres/share/postgresql
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

Can anyone help me out ?

Thanks,
Saket.
