Hi Bill,
Thanks for the suggestion. It turns out there are no man pages
for any of the 3 symbols. Because these functions are defined
in src/gleap/mortsrc/nablib, I had assumed that these are
either AmberTools functions or that they would be built as
part of building AmberTools (that is, they are not part of
other C++ or system libraries). Is this correct?

It is strange to me that it appears that libmort.a was built
correctly and the 3 symbols appear to be defined there.
The output of 'nm -A libmort.a' contains:

libmort.a[traceback.o]: .rt_errormsg_s T 224
libmort.a[memutil.o]: .imatrix T 688
libmort.a[memutil.o]: .matrix T 1056

Doesn't this mean that these symbols are defined in libmort.a?
If so, why can't ld resolve them?

Any ideas?
Thank you very much!!
