If they are present on all the cluster nodes it should be ok - no reason

Ah, that could be it. Different versions of LAM are *NOT* compatible 
with each other according to the LAM homepage homepage, you have to run 
the code with exactly the same version of LAM as you used to compile it. 
Either install the lam package from the gromacs homepage, or compile it 
(it's easy) on your system. I'd recommend the latter :-)
