I'm a bit confused at this point.  By 64-bit binary, I assume you mean
built so that it uses 64-bit pointers, correct?  Are you also using
--enable-64?  I would expect --enable-64 to fail unless you have also
built your BLAS and LAPACK so that they use 8-byte integers for
indexing arrays.  This is a separate issue from whether you are using
a system that has 64-bit pointers.

In addition to BLAS and LAPACK, there are other numerical libraries
that also need to be compiled to use 8-byte integers for array
indexing.  See the install.txi file for more info about which ones.

Does building in 64-bit pointer mode but without --enable-64 work?  If
not, what error do you see then?
