Progam is called "cpanflute2" and perl module is RPM-Specfile, I use version 1.17 and it builds perfectly on CentOS4.
cpanflute2 MODULE.tar.gz
thanks got it to work :) just trying to figure out how to get it to end up in vendor_perl and not site_perl, but that's probably not-important...
Anybody use the following? http://rpmpan.sourceforge.net
