Michael,
i will followup on that in the devel mailing list.
imho, there are three ways to see this :
1) this is an environment (e.g. user) issue: if you want it to work,
then slurm should be rebuilt with pgi compiler.
2) this is a libtool issue : it does not support mixing .la files built
with gcc and pgcc (e.g. -pthread option is unknown by pgcc)
3) this is an other libtool issue : -noswitcherror should be passed by
libtool to the PGI compiler
Open MPI is not to be blamed here.
that being said, i am pragmatic so i do not mind hacking (one more time
...) libtool in OpenMPI to fix libtool or even make it PGI/GNU friendly
Cheers,
Gilles

as a workaround, you can configure without -noswitcherror.
after you ran configure, you have to manually patch the generated 'libtool'

i guess the right way is to patch libtool so it passes -noswitcherror to $CC
and/or $LD, but i was not able to achieve that yet.
Thanks. I managed to work around the issue, by hand compiling the
single module that failed during the build process. but something is
definitely amiss in the openmpi compile system when it comes to pgi
