This really should be in a FAQ somewhere (preferably easily accessable)

The reason this happens is that the pvmgetarch shell script for reasons
unknown only returns LINUX if you have a CPUT that is identified by
i386, i486, or i586. My Cyrix chip identifies itself as a i686, and the
script fails.

The fix is really easy. On line 55 of pvmgetarch (for pvm 3.3.11), alter
the line:

        Linux,i[345]86 )       ARCH=LINUX ;;

to detect you CPU. I just had to add a 6 inbetween the []s. ie:

        Linux,i[3456]86 )       ARCH=LINUX ;;

You can find out what you CPU reports itself with the command :

"cat /proc/cpuinfo"

The number returned for the cpu (line 2) should be your CPU. Mine says
686, I don't know what yours will return. You could add 6, 7, 8, and 9
if you really wanted to.
