Error on make of ftconv.exe not finding -lf2c

[Nick Wilson]

Dear Bill,

It looks as if the lapack which comes with the operating system needs 
the f2c library but if you use an optimised blas such as mkl or atlas 
then you don't need to install the f2c package (and should get better 
performance)

Best wishes,
Nick Wilson
