ok, so the intel people either seem to compile parts of their lapack 
libraries with g77 or use the f2c runtime (conventions). ;-). 
should be rather easy for them to include a stripped down run-time
in their library.

there are two likely causes: you have not installed the same version of 
LAM on all nodes that you are using, or the network does not work 
properly.

so please try running the parallel executable only with one node,
and - if that works - lamboot only one node, but run two copies and
if that works too, please carefully whether the new lam on the additional
nodes is really in the search path and of the same version.

hope this helps,
