ourdelta provide MySQL packages for various platforms, built with assorted performance/feature patchsets.

Sadly, like the percona builds, the RPM packages for RHEL/CentOS are not upstream-compatible, ie. they package MySQL differently.

I was planning to re-build the ourdelta packages to use the upstream RPM package layout but I've decided to stick with re-building the percona packages as I've already done the work for that.

Anyway, in case it helps someone, here's how to rebuild the ourdelta packages from the SRPM:

rpmbuild --rebuild \
  MySQL-OurDelta-5.0.87.d10-65.el5.src.rpm \
  --define 'ourdelta 1' \
  --define 'mysqlversion 5.0.87' \
  --define 'elversion 5' \
  --define 'patchset d10'
