scons can probably (if it doesn't know already somewhere else) be taught to
fish up the
answer to lib vs lib64 based on how the python is built. python has internal
variables
documenting its lib locations you could check for /lib64/ vs /lib/
in the non-scons world, lib vs lib64 is determined by the person building
saying '--libdir=${exec_prefix}/lib64'

I'm not sure what we can do about the SWIG bug. I had an email back from
one of the SWIG developers, William Fulton, requesting a small test case
to exhibit the problem, but haven't had time to produce one.

As for CUnit, it should be possible to compile ASCEND without using
CUnit. That is only needed for building our test suite. The current
CUnit-based test suite makes no use of ncurses. My version of CUnit has
no ncurses dependencies, so I guess this could be an issue with your
build of that library?

You're talking about changing the installed library location, is that
correct? When building an RPM this should flow through the .spec file to
INSTALL_LIB automatically, and I think that that is a fairly good
solution, perhaps? Arch detection is tricky to do with full generality
-- eg config.guess, so if we don't have to do it, that's better.
