Hi Javi

BlueGene is a tricky platform.  Um... maybe it's easier if I just stop
by your office tomorrow morning and we can sort this out in person.

It looks like you are building ROMIO for the login node, which will
create an executable and/or library that will not work on the compute
node. 

Building all of MPICH2 for BlueGene requires also building DCMF (the
BlueGene communication library).  Building just ROMIO might work, but
there is no native PVFS support on the compute nodes.   The Compute
node OS just can't support many of the calls in libpvfs2.a
