Hi, sorry for the delay.
I'm not very familiar with the workings of ltdl, I got this from one of our
users. Would you suggest that if one use openmpi 1.3 and ltdl you should not
explicitly link with -lltdl? At least this seems to work correctly with the
example I posted. That is, I can link the program without specifying -lltdl so
the symbol seems to resolve to something in the openmpi libraries and the
example runs without crashing.
