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.9519MULTIBYTE= MULTIBYTEID=0 POSTGRES_SUPERUSERNAME=baron POSTGRES_SUPERUSERID=1

This database system will be initialized with username "baron".
This user will own all the data files and must also own the server process.

FATAL 2:  InitReopen(logfile 0 seg 0) failed: No such file or directory

initdb failed.
Data directory /boot/home/pgsql/data will not be removed at user's request.              
   any idea ?
