help wanted with installation MySQL under SGI Irix.

I've got an SGI O2 running Irix 6.5. From the SGI freeware download pages I
downloaded MySQL for Irix 6.5. I let the computer do the basic installation.

After this installation I was not able to run mysql.
I tried to startup de deamon with
> mysqld_safe &
and
> mysql_safe --user=mysql &

The current system will not startup de mysql server.

Some extra info:
The user mysql is known to the system. All read and write rights seem to be
in order.

At the bottom I added some log-output. The file "host.frm" (and others) are
available under "/var/spool/mysql/mysql"

Gruptek,
Arno.
