You gave me the inspiration for the fix.  SUSE 9.1 uses a version of 
'ps' which does not like the '-'.  I edited config.h to change:

#define PS_COMMAND "/bin/ps -axwo 'stat uid ppid vsz rss pcpu comm args'"


#define PS_COMMAND "/bin/ps axwo 'stat uid ppid vsz rss pcpu comm args'"

All now works perfectly.

If I knew more about 'autoconf' I would offer a better fix.  As a start 
I can see the environment variables:

BASH_VERSINFO=([0]="2" [1]="05b" [2]="0" [3]="1" [4]="release" 

Hope this is of some use.

Regards, Ben.
