This is probably not the best place to add this flag. It is perhaps better
to add it when enableOptimize=1 is given. For now, you can use the option
customCxxFlags to add the -DNDEBUG flag, i.e.

    scons customCxxFlags="-DNDEBUG"

Well, it did find a pkg-config file for UMFPACK, however, it failed when
resolving compiler or module dependencies. What does your umfpack.pc look
like? Does it specify a compiler? That could probably be the issue here.

Can you show us the contents of scons/simula_scons.log?
