Initdb not running on beos

I've a problem with initdb on beos with the current tree. (The last one
running clean is one month old).

when I run initdb, I get the following :

$ initdb -d -n
Running with debug mode on.
Running with noclean mode on. Mistakes will not be cleaned up.

Initdb variables:
PGDATA=/boot/home/pgsql/data
datadir=/boot/home/pgsql/share
PGPATH=/boot/home/pgsql/bin
TEMPFILE=/tmp/initdb.9519
MULTIBYTE=
MULTIBYTEID=0

PG_IDENT_SAMPLE=/boot/home/pgsql/share/pg_ident.conf.sample
This database system will be initialized with username "baron".
This user will own all the data files and must also own the server process.
