Re: initdb fails on ultra2 sparc64, freebsd 5.4

On a Sun ultra2 sparc64 initdb hangs.
cpu0: Sun Microsystems UltraSparc-I Processor (200.00 MHz CPU)

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

The database cluster will be initialized with locale C.
