Hi,

gem2deb is a dh buildsystem, so it's called by debhelper for each
action, such as configure, build, test, install, clean.

but it's also a dh sequence, so it can plug itself at any point of the
debhelper build. For example, it's done after dh_shlibdeps to hack the
dependencies for packages building native extensions.

You could easily insert into the dh process to override dh_compress that
way. See debhelper7/sequence/ruby.pm for details on how it is done for
dh_shlibdeps.
