Me, too.
make -f makefile.linux is enough.

I didn't need that due to LSB.

ditto

I think my is much older, but 6.1.2 anyway;-)

I had to add the below few lines to EnvLINUX.c as someone pointed out, 
yesterday.
Then all is smooth.

/******************************************************************************
 *
 * GetNumProcessors - return number of processor on system
 *
 * Description:
 *  For MP execution, then number of processors is used for identification of
 *  of the number of graphics threads to exploit.

 * Returns:
 *  integet number of processors
 *
 * Side Effects:
 *  none
 *
 * Errors:
 *  no errors, if function fails the string 1 is returned
 *
 * Revision History:
 *    Initial Release
 *
*****************************************************************************/
int
GetNumProcessors()
{
    return (1);
}

It gave no performance increase because I have a single CPU system but I am 
running lastest O(1) and preemption stuff. So it is even so _NOT_ slower.
And my Athlon XP/MP is still around...;-)

Thanks to all who answered.
