Crud.  You are correct.

The VERSION string for the f90 library was incorrectly updated to 4:0:1; it 
should have been updated to 4:0:3.

I have fixed this for v1.6.4.  I'm *anticipating* that there aren't may people 
who will be bitten by this, so for the time being, at least, I'm publishing 
this workaround:

1. Download Open MPI v1.6.3
2. Untar it, configure it
3. BEFORE you build it (but AFTER you ran configure!), edit 
ompi/mpi/f90/Makefile
4. Change line 1212 from

libmpi_f90_so_version = 4:0:1

to

libmpi_f90_so_version = 4:0:3

5. Then make the "all" and "install" targets as usual.

If this workaround suffices for those affected, I'd prefer to release v1.6.4 
with this fix after Supercomputing (i.e., early/mid December).  Please let me 
know.
