Hint: simply typing 'ant' will have the same net effect as the above  
command. If Ant encounters a build.xml in the directory where it is  
started, then it automatically picks it up and starts the build.

I personally only ever supply parameters to Ant if I need to run a  
specific build target.

If I interpret correctly, this is definitely not something you're  
doing wrong.
It only seems like the JEuclid API has changed, and is currently  
incompatible with the FOP MathML extension...

Someone on the FOP-side needs to update our extension code.
A possible (temporary) workaround: try to find an older version of  
the JEuclid JAR.

Cheers,
