Hi everybody,

I am encountering some strange problems enabling TeX support in my wiki. I am running the latest Bitnami MediaWiki stack. I have followed all steps from the tutorials.

Still, whenever I try to render a latex formula, I receive the error message

Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert)

As I have followed all steps from the tutorials, I started debugging a little bit. Obviously, the latex command in the file render.ml fails:

#render.ml .... if Util.run_in_other_directory tmppath (cmd_latex tmpprefix) != 0 ...

The output of this command is

dyld: Library not loaded: /opt/local/lib/libpng12.0.dylib Referenced from: /opt/local/bin/latex Reason: Incompatible library version: latex requires version 36.0.0 or later, but libpng12.0.dylib provides version 35.0.0

This error message seems really strange to me, because latex is not using png here (just creating a DVI from a TEX file), and to the best of my knowledge there is not even a 36 release of libpng.

Do you have any idea how to proceed here? From the command line everything works fine.

Best regards, Stephan
