That sounds vaguely familiar. Didn't somebody mention a patch for this
recently?

Compile on a clean build machine and just install the package on the ones
with a broken build environment?

I suspect you'll find that glusterfs is still undergoing a sufficiently
rapid development and stabilization process that staying a few versions
back is very counterproductive. In the majority of releases more gets fixed
than broken, so I wouldn't even bother reporting an issue with an older
version unless you have verified that it is still broken in the latest
release (unless it's a regression, i.e. something that used to work but got
broken in a newer version).
