I am now looking at using IBM's XLC compilers for ILP32 builds on the
same Linux/PPC64 platform for which I've reported some XLC/LP64 bugs.
What I find now is that "make check" is failing with the loader unable
to find libmpi.so.0.
This is with both 1.5rc5 and 1.4.3rc1.
This occurs with xlc, but things are just fine with gcc.

Here is the configure command:

The problem exists with both 1.5rc5 and 1.4.3rc1.
Here is the failure from 1.4.3.rc1:

Here is 1.5.rc5, which I suspect differs only because the two releases
contain different tests:

As I said above, the problem is NOT occuring w/ gcc. So, I've attached
the "./libtool --config" output for the xlc and gcc builds, which I see
differ in more ways than I would have expected.
