Three ideas:
1. Just unset your MKL_HOME variable, so you don't use MKL at all. The
performance advantage of MKL is really pretty small, and if all you have are
old MKL libraries, it may be easily more trouble than it is worth to try to
fix things.
2. Read the documentation from intel on how to compile x86_64 codes with MKL
version 9, then manually edit your config.h file to comply with such
information. It seems very likely that you don't want to use libmkl_ia32.a.
If you figure it out, post the solution -- it really looks like the -oldmkl
option in configure may be broken.
3. Maybe someone on the list still uses MKL version 9, and can chime in about
what to do.
....good luck....dac
