'header.tex' not found when running example

[ghost]

I'm attempting to run the script using the 'example.tex' file, but it errors out when pdflatex attempts to convert the equations. I've tried this on 2 OS's (OS X and Fedora 20), and I get the same error. Any idea why? Am I missing a TeXLive dependency? Full error output is below.

i made a change , does it work now ?

Partially. The 'header.tex' error is gone now, but now I get another error stating that it can't find 'equations/eqn1.png' (below is the output). I was able to fix the problem by replacing lines 131 and 142 with file=os.path.join('eqn%d.png'%ideqn), so the equation .png's are just placed in the working directory. That or I can just manually make a directory called 'equations' and leave the script as-is. Thanks for putting this code out on github, I'm sure its going to save me quite a bit of time in the future! --David
