Certainly. The build comes from git://sourceware.org/git/pcpfans.git branch fche/pmfuntools, which is regularly rebased on top of pcp master, as long as we have features that have not yet been merged upstream.
The big ticket item is "pmwebd -J", a new default option that dramatically speeds up pmwebd when processing graphite queries against a potentially huge set of archives, and allows representation of a barely-mangled hostname (instead of a highly mangled archive path name) as the first component of the graphite metrics.
From [man pmwebd]:
-J When constructing graphite metric names, use the stored hostname instead of a archive pathname as the first component. This virtually unifies all archives found with the same hostname into a single time series. The host name is canonicalized: any symbol characters other than _ (underscore), space, - (hyphen), and / (slash) are replaced by _ (underscore).
