I have overseen the time stamps above.  Actually, after a git clone, 
oct-gperf.h is older than octave.gperf.  This triggers the building of 
the former and, hence, make the package build fails, because gperf is not 
installed.

Touching the target file seems to fix the problem:

    touch libinterp/parse-tree/oct-gperf.h

I am considering adding this to d/rules.  Any objections?
