It seems that the comanche package is not in the RPMS directory of the rh 6.1 distrib. Is it somewhere else or has it been left away ? So far, I've installed the package coming from rh 6.0 but people new to redhat might be surprised.
comanche is unmaintained at this point and simply had too many problems to continue being included in the distribution. We should have a much improved apache configuration tool in a future release of Red Hat Linux.
