I did, on various Unix machines in the past, although I haven't tried
with the atlas package yet.
In general, there are two problems you can run into:
1) There are different conventions for mapping names from Fortran to C.
The BLAS/LAPACK interface in NumPy supports two of them (identical
names or appended underscores), but there might be more. Changing
this is simple, just scan through the interface code and replace
the symbol names.
2) The Fortran code might rely on external support libraries. Under Linux,
this shouldn't be more than libf2c, so adding -lf2c should be sufficient.
