new formula: mathgl

[ptxmac]

MathGL is a library for drawing graphs/plots and mathematical formulas (and more)

Coincidentally it seems I wrote a mathgl formula at the same time you did (#11399).

I wasn't able to get yours to work on Lion. During configure I get

checking png.h usability... no
checking png.h presence... no
checking for png.h... no
Please install png headers
==> make install
make install 
make: Nothing to be done for `install'.
==> Finishing up
ln -s ../../Cellar/mathgl/1.11.2 mathgl
==> Summary
/usr/local/Cellar/mathgl/1.11.2: 6 files, 96K, built in 5 seconds

I believe this is resolved via the ENV.x11 call (check out my pull request). I also had to play around with libz, since the new libpng included in Lion doesn't work with 1.11.2 without patching.

Does mine work for you?

It almost works, you forgot to add gsl as a depend_on. Otherwise it works fine.
