Compiling from source would have been the next suggestion. Seems that I 
need to creccomend that earlier.

 From what I have read in the link you posted it seems to be a problem 
when they have built the package.

It would be interesting if the RPM Package on SF has the same problem.
I just wrote the note on the site you have mentioned.

auf hoffentlich bald,
