I got todays master from openembedded-core and meta-openembedded, and 
the recipe above (with a fix for the license). I leave everything as the 
script "oe-init-build-env" does, I only add meta-openembedded/meta-oe to 
the bblayers.conf list to get access to the gitpkgv class.

I named the recipe above "weirdversion.bb", and when I build it "as is", 
I get the correct version number "z-pkgv+68+2e7a1db-r0" (with "pkgv" and 
"68" in it).

However, when I add the following line to local.conf to activate the 
PR-SERVER, things go wrong:

PRSERV_HOST = "localhost:0"

After this change, the package suddenly gets "z-pv+0+2e7a1db509-r0.0" as 
version string, so apparently the PR server kills the PKGV variable and 
replaces it with something derived from PV alone.

Since this is a completely clean situation with nothing but core code, 
it must be a bug in the PR server (it seems to act as PV server instead...).
