I recently built some packages that are not available as binaries yet. To
make these available to others, the instructions suggest I use the
command

make package

but this tries to fetch the original tarballs and rebuild the package. (I
deleted the tarballs after installing.)

Is there a quick way to generate a binary package from a package installed
on my system without requiring any rebuilding, or the original files? (I
haven't yet done a make clean if that makes any difference.)

Thanks

Ian
