I am getting some undefined references in building OpenMPI 1.5.4
and I would like to know how to work around it.
The errors look like this:

S ome configure output that is probably relevant:
checking numaif.h usability... yes
checking numaif.h presence... yes
checking for numaif.h... yes
checking for set_mempolicy in -lnuma... yes
checking for mbind in -lnuma... yes
checking for migrate_pages in -lnuma... yes
The FAQ says that I should have to give –with-libnuma explicitly,
but I did not do that. Is there a problem with configure? Or the
FAQ? Or perhaps the system has a configuration peculiarity?
Last time somebody complained about this, he was trying to build
fully-static binaries but libnuma was only available as dynamic
libs. Configure only checks for dynamic libs. So it thinks libnuma
is available while the required static libnuma was actually missing,
causing make to fail later.
How did you configure and build, what's your distro, and do you have
libnume static/dynamic installed ?
There is also a FAQ if you need fully static binaries:
