I am trying to build OpenMPI using Lahey Fortran 95 6.2 on a Fedora Core 3

It appears that it is bombing out when it is building the Fortran libraries.

Hello,
Testing the MPI_Comm_Spawn function of Open MPI version 1.0.1, I have an
example that works OK,
except that it shows that the spawned processes do not follow the
"machinefile" setting of processors.
In this example a master process spawns first 2 processes, then
disconnects from them an

as far as I know, Open MPI should follow the machinefile for spawn
operations, starting however for every spawn at the beginning of the
machinefile again. An info object such as 'lam_sched_round_robin' is
currently not available/implemented. Let me look into this...

We expect to have much better support for the entire comm_spawn process

so for my tests, Open MPI did follow the machinefile (see output)
further below, however, for each spawn operation it starts from the very
beginning of the machinefile...
The following example spawns 5 child processes (with a single
MPI_Comm_spawn), and each child prints its rank and the hostname

This sounds like a problem that we just recently fixed in the 1.0.x
branch -- there were some situations where the "wrong" ethernet
device could have been picked by Open MPI (e.g., if you have a
cluster with all private IP addresses, and you run an MPI job that
