You want to try out the latest Pyramid build from Metrix's Subversion repository, instead of the official stable release. It has some features you want, or you want to contribute to the project by testing new builds.
You'll need a PXE boot installation server to make this work. Use the pyramid-export.sh script available from http://pyramid.metrix.net/trac/wiki/GettingPyramid to download the latest build and roll it into a tarball. Then, copy the tarball to your HTTP document root directory, and run the PXE boot installation in the usual way.
