Hi,

I have started again, simply executing:
>python setup.py install

However, I now get the following:
>File "numpy/core/setup.py", line 253, in check_mathlib
>  raise EnvironmentError("math library missing; rerun "
>EnvironmentError: math library missing; rerun setup.py after setting the MATHLIB
>env variable


I have a math library from cygwin (libm.a).

How should I set this?

Thank you,

Olivia
