h1. Requirements

Please make sure to follow the instructions for compiling python prior to building ROOT since ROOT needs to be built against python.  ROOT may also be built against MySQL on the linuxes.  Also note that often the version of the source we utilize for ROOT is Fermi-specific where patches have been applied or the version of ROOT is from a branch from their Subversion repository.

h2. v5.20.00-gl5

We ran into a problem this time with distribution of our linux build for ROOT.  It seems prefix cannot be used, so we must set the ROOTSYS env var for our build.  make install no longer seems to work unless prefix is used, so we are left to prune the resulting ROOT build directories on our own.
