LatexModePlugin installation help needed

Hi all!

I shall install the LatexModePlugin extension. I have to say that somebody tried it and now its my task...

I updated the plugin to the newest version and enabled it, but nothing worked... Then i found the install-instructions on the following page: http://foswiki.org/Extensions/LatexModePlugin

there, the following is mentioned:

Plugin Installation Instructions

First, confirm that the external software needed by the plugin is installed on the Foswiki server. This includes:

The Digest::MD5 and Image::Info perl modules.
A mechanism to convert LaTeX markup to images. This is either
- A working LaTeX implementation (tetex and MikTeX are two popular choices)
- the 'convert' executable from either ImageMagick or GraphicsMagick
- dvipng and/or Ghostscript
or
- mimetex

Rendering can be performed by ( latex and dvipng) or ( latex and dvips and convert) or ( pdflatex and convert) or ( mimetex). The first three options allow one to include almost any LaTeX markup in a Foswiki topic, whereas mimetex has very limited functionality. Among the first three options, dvipng is the fastest by a significant margin. The tweakinline processing (v2.5 and above) to align the baseline of LaTeX expressions with HTML text uses convert. mimetex can be used in server environments where a full LaTeX installation is impractical (e.g. on shared-server installations). mimetex provides rendering of equations independently of external font files. This provides a very lightweight and fast mechanism to show equations. However, the number of colors is limited to 4 (black, red, blue, green) and only the mathmode and picture LaTeX environments are supported. Also, the preamble, density, and gamma settings are ignored.

Our IT department chose the mimetex solution and installed mimetex on the system. Now I read the following what confused me:

Now, customize the installation specific configuration settings.

Set the local disk paths for the rendering methods employed. This can be done by copying the needed lines from the following list to lib/LocalSite.cfg
- $Foswiki::cfg{Plugins}{LatexModePlugin}{latex} = '/usr/bin/latex';
- $Foswiki::cfg{Plugins}{LatexModePlugin}{pdflatex} = '/usr/bin/pdflatex';
- $Foswiki::cfg{Plugins}{LatexModePlugin}{dvips} = '/usr/bin/dvips';
- $Foswiki::cfg{Plugins}{LatexModePlugin}{dvipng} = '/usr/bin/dvipng';
- $Foswiki::cfg{Plugins}{LatexModePlugin}{convert} = '/usr/X11R6/bin/convert';
- $Foswiki::cfg{Plugins}{LatexModePlugin}{mimetex} = '/usr/bin/mimetex';

which lines have to be added? I added all of them and enabled the plugin, created a site with the example from the extension page (This is an example of the %BEGINLATEX{inline="1" density="200" gamma="1.0" color="Purple"}%\LaTeX%ENDLATEX% rendering possibilities using the LatexModePlugin.) and an error occurs.

When i reduce it to the line

$Foswiki::cfg{Plugins}{LatexModePlugin}{mimetex} = '/usr/bin/mimetex';

then i still get errors...

The error looks like this:

Software error:

Any suggestions??
