RPM building

Hi, I'm using SUSE as the basis for an Open Source GIS workstation, on an AMD64 platform. To date, I have been compiling the requisite packages from source, but I'm now looking to build RPM's and make these available. The software involved includes Postgres, Postgis, GEOS, Proj4, GDAL (OGR), QGIS, and a few other utilities and libraries. I'm not a programmer/developer, and am after advice or a mentor to help me with this. Is this list an appropriate place, or is there somewhere better? Thanks, Brent Wood
