Description of problem:

When you try to convert a .tex file that includes the pslatex package and has equations into a .rtf file using latex2rtf and -M12, you will have errors in the equations conversion because GS_FONTPATH is not set correctly.

pslatex package (http://ctan.org/pkg/pslatex) makes LaTeX use the standard PostScript fonts, like Times. The -M12 in latex2rtf convert inline and displayed equations to .png. Thus, if a .tex file has equations and pslatex packages, then the conversion of such equations into .png file will fail with "invalid font" errors, because the default ghostscript fonts path in Fedora are not set (GS_FONTPATH environment variable).

Version-Release number of selected component (if applicable):

I'm using latex2rtf 2.2.0 (Fedora 17)

How reproducible:

I could reproduce this bug every time I try to convert a .tex that has equations and pslatex package into a .rtf using latex2rtf with -M12.

Steps to Reproduce:
1. Create a .tex file with inline and displayed equations and pslatex package (or download test.tex attached)
2. Compile with pdflatex (everything should work fine)
3. Try to convert to a .rtf file using latex -M12 -D300 <NAME>.tex
  
Actual results:

You will see errors about 'invalid font' (see attached error log for the conversion of test.tex).

Expected results:

The conversion should work correctly.

Additional info:

The problem is gone if you use the command:

GS_FONTPATH=/usr/share/fonts/default/Type1/ latex2rtf -M12 -D300 <NAME>.tex
