Its not the 'rts' libraries. blrts_xlc doesn't use any rts libraries.
And this example code gives the same error with it. [and the gcc cross
compiler]

I guess it just that - with crosscompiling [which is what we are doing
on the bgl] - you can't expect the binaries to run on the front end
node. trivial examples happen to run on the front-end nodes - due to
the many similarities between frontend/compute nodes.
