Was lam compiled with g95?

The error message (from lam, not from Amber!) is very misleading here. It
actually has nothing to do with mpif77 not being present...

Try leaving out the -lvml. This was put in based on earlier versions of MKL,
and might not be appropriate for MKL version 10. Note that most people who
have MKL also have the Intel compilers, so that the g95/MKL combination is
probably not very well tested. If you continue to have problems, certainly try
leaving out MKL...its presence or absence doesn't really make a big
difference, except maybe for some GB simulations.
[And, if you have the ifort compilers licensed, consider using them. They will
certainly provide a performance improvement over g95.]
