Don't they still support CALL PXFSYSTEM?

IIRC the compiler provided with the XT3 is Portland, and according
to

http://www.polyhedron.com/pb05/linux/language.html

it doesn't support the PXF* stuff. Actually, except for ifort none of
the tested compilers support it.

Again, according to the above link all the compilers seem to support
some kind of "Invoke External command" feature, so I don't know why it
wouldn't work on the XT3. Yes, the XT3 is special in that most
syscalls on the compute nodes are not handled by the compute node
kernel but rather forwarded to one of the IO nodes, but Cray claims
some level of POSIX support so I guess it should work. But apparently
it doesn't. Perhaps Joost, who apparently has actual experience with
the thing, can explain?
