initdb failed

Upon installing and configuring PostgreSQL completely fine - no errors, I go
to run initdb... and:

gnuworld@userservice:/usr/local/pgsql/bin$ ./initdb -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user
"gnuworld".
This user must also own the server process.

initdb failed.

Why is this occurring, how can it be fixed?  tcl8.3, PostgreSQL 7.2,
FreeBSD-4.5, gmake-3.79.1
