Sorry for the delay in replying.
Looks like this was fixed already in OMPI 1.2.5. So if you upgrade to
1.2.6, you should be good. 1.2.7 should be out Real Soon Now, too.

From the FAQ:
http://www.open-mpi.org/faq/?category=building#build-compiler-flags
LDFLAGS: Flags passed to the linker (not language-specific). This
flag is rarely required; Open MPI will usually pick up all LDFLAGS
that it needs by itself.
