>Description:
math/py-numpy is broken on 9.2-STABLE by the change of the default gcc version to 4.7. I tried to compile everything related to numpy with gcc48 as recommended by someone, but the error stays the same (sans version in the path in ImportError line below):

 $ python -c "import numpy"

I have seen the discussions in December in preparations for the GCC version change. It seems the patch proposed in there, is in place (/usr/ports/math/py-numpy/files/patch-numpy-distutils-fcompiler-gnu.py), but apparently it's not enough...

I also tried to rebuild all my ports. I did it with portmaster in-place method, though, which is not totally free from inheriting problems of previous builds.
>How-To-Repeat:
I see the discussions of the same bug, e.g. as py-scipy build problems. So I guess it's easy to reproduce with fresh ports on 9.2-STABLE...
