Description rgb 2013-04-02 23:23:37 UTC 
Steps to reproduce the problem:

1- Create a new page on the wiki
2- Insert a math expression, something like  <math>E = m.c^2</math>

What happens:

When you try to render the page, either by saving it or using the preview, you obtain an error message:

Failed to parse (Missing texvc executable; please see math/README to configure.)

Note that mwiki make heavy use of cache, so older pages with math objects are presented without problems, but new pages (or new objects on old pages) do not work. 

It seems this problem happened before (see Bug 121516, marked as "fixed").
