3.0 Pre2 install

[Richard Humphrey]

I had the same problem when trying to build rpm from tar ball on pre1. I 
renamed pre1 to remove the -pre in the name and once doing that it 
worked.  On pre2 when I remove the -pre2 from the name it is named 
Mail-SpamAssassin-3.0.0.tar.gz. When I run the following I still have 
problems.

]# rpmbuild --tb Mail-SpamAssassin-3.0.0.tar.gz
error: File /root/Mail-SpamAssassin-3.000000.tar.gz: No such file or 
directory

What should I rename this to exactly?
