That's why you should use fppkg, and not fpmake directly. (fppkg is in
this case only a wrapper, compiling fpmake when necessary and adding
default parameters from it's configuration file to fpmake)

With fppkg -v you can see how fppkg calls fpmake.

'fppkg list' scans for all those files and shows which versions are
installed.

If uses the same algorithm as Fedora uses for all their packages. And
you can imagine how many different version-number-systems there are for
all those packages. ;)

In you care the version-number should be: 0.7.166-g010ab.

A subversion-version could be something like (see the lnet package)
x.y.z-rxxxx
