7.4.2 initdb problem

I've installed 7.4.2 on a PowerPC system running linux 2.4.13. When I
try to run initdb to create to create the database cluster I get the
following:

$ initdb -D $PGDATA

The files belonging to this database system will be owned by user
"thebox".

This user must also own the server process.

The database cluster will be initialized with locale C.

I'm at a loss as to where I should look for the problem.

Any guidance will be greatly appreciated,
