Do you have any notion of why this is showing up now and not earlier?

Do you think it is specific to Frameworks? I don't see any problem with MKL
under Linux. My code is also searching libmkl_intel_lp64.a.

Aha: on linux (icc) if I do this:

   cd amber11/lib; nm libnab.a | grep second

I see that libnab.a is defining "second"; however, if I do the same
on a Mac (with gcc), libnab is exporting "_second". And MKL is also
exporting "_second". What compiler are you using?? And what do you get
on your system with the above nm command?

Don't do anything right now to the code; I think we can eliminate all
references to second() pretty easily. But it would be nice to track down
exactly what combination is failing.
