I reran the build as Ralf requested (setting
shlibpath_overrides_runpath=yes in the libtool script).
The build and check were SUCCESSful!
I have provided Ralf with the requested files off-list.

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.
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.
The thing that's unexpected to me is the shlibpath_overrides_runpath
difference.
While I still don't know the root cause, the following diff between
the libtool-generated wrappers for a gcc and xlc build make the
cause of the "make check" failure fairly obvious:
Please set shlibpath_overrides_runpath=yes in the libtool script for
xlc, then try 'make clean all check'. Please send config.log for xlc
(packed).
Thanks,
Ralf
