You didn't kinda accidentally upgrade python without running python-updater or something? :) If that's not the case, is numpy installed properly?
Can't reproduce locally, run python-updater :)
I re-runned python-updater just to be safe, and it is still failing.
Try emerge -1 dev-python/numpy.
If numpy is emerged for python-2.6, this file must exist, and be owned by the numpy package. If it does not exist, something is wrong with your numpy installation.
I ran python-updater, rebuilt numpy, etc... The build still fails, but the errror seems different now, I am uploading the new build.log mgl2gif.cpp: In constructor 'Str::Str(Str*, const char*)': mgl2gif.cpp:55: error: 'mbstowcs' was not declared in this scope mgl2gif.cpp: In function 'int main(int, char**)': mgl2gif.cpp:102: warning: ignoring return value of 'wchar_t* fgetws(wchar_t*, int, __FILE*)', declared with attribute warn_unused_result make[1]: *** [mgl2gif-mgl2gif.o] Error 1 make[1]: *** Waiting for unfinished jobs.... libtool: link: i686-pc-linux-gnu-g++ -Wall -DNO_GSL -O2 -march=pentium4 -fomit-frame-pointer -pipe -Wl,-O1 -o .libs/mgl2png mgl2png.o ../mgl/.libs/libmgl.so -L/usr/lib /usr/lib/libpng12.so -lm -lz /usr/lib/libGL.so /usr/lib/libXmu.so /usr/lib/libXt.so /usr/lib/libXi.so /usr/lib/libXext.so -lpthread /usr/lib/gcc/i686-pc-linux-gnu/4.3.3/libgomp.so -lrt /usr/lib/libgif.so /usr/lib/libSM.so /usr/lib/libICE.so -luuid /usr/lib/libX11.so /usr/lib/libXau.so /usr/lib/libXdmcp.so /usr/lib/libjpeg.so /usr/lib/libltdl.so -ldl make[1]: Leaving directory `/var/tmp/portage/sci-libs/mathgl-1.8.1/work/mathgl-1.8.1/utils' make: *** [all-recursive] Error 1 [31;01m*[0m [31;01m*[0m ERROR: sci-libs/mathgl-1.8.1 failed.

I use gcc-4.3.2-r3, and have giflib-4.1.6-r1. Compiling mathgl-1.8.1 with USE=gif succeeds.
Finally... The patch worked great... thanks!!!
Good. Closing.
