Help creating a rpm build system

Hi, I'm trying to create a rpm buildsystem based on rpmfusion. It's purpose is to create custom rpms for my research department lab. I have setup plague builders and a server and I'm trying now to make it work with CVS. My CVS is based in rpmfusion's (which in turn is based in epel). When I try to add a new package to my cvs with addpackage, I get the following error: ERROR: 'setup_package' is not in the path. setup_package is run by mkbranchwrapper, but I can't find setup_package in fedora's infrastructure. I doesn't seems to be provided by any package either. Any help? -- Sergio Pascual http://guaix.fis.ucm.es/~spr Departamento de Astrofísica -- Universidad Complutense de Madrid (Spain)
