description:
+ By default, support user-destdir installation as the gem installation
  process makes that easily possible.

+ Use ${EXTRACTOR} to manually unpack the gem file.

+ Change the do-gem-install target to initially build and install the
  gem into a buildroot, ${WRKDIR}/.inst, then to copy the files from
  the buildroot into the final install location, ${DESTDIR}${PREFIX}.

XXX We still need to find some way to remove the intermediate build
XXX files, e.g. *.o object files, from the buildroot before copying
XXX to the final location.
