tetex 3.0.0-1 installation

[m. z.]

I tried to install tex/latex 3.0.0-1 (last version), but I did not succeed. 
The setup, when arrives at /etc/postinstall/post-texmf.sh , I think 
something wrong it happens, since I waited for more than 30 minutes (with 
Pentium 4) consuming up to 100% of CPU and not proceeding. I had to stop it 
and to reinstall the previous version 2.0.2-15.
Any suggestion on how to succesfully upgrade my tex ? Or Is it a bug of the 
last version ? Someone succeeded in installing it ?
Thank you
