Sorry if this is old news, configuration problem, or whatever. I have
been tied up with other things, and have not been able to follow ompi
very closely.

I just built openmpi-1.0a1r7305 for testing, and notice that ompi_info
(and all other ompi tests) give
mca: base: components_open: component linux open function failed
and eventually terminate with a Seg Fault. Interestingly, the programs
do seem to run pretty much correctly otherwise.

System is sparc/linux (sparc64 in 32-bit user mode, SB1000).

Output from 'ompi_info -a' is attached.

Regards,
