Both are complete in the attached "v4" tarball.

It should be easy enough to disable with the knobs provided, either
DISABLE_RAR=1
or DISABLE_RAR_COMPRESS=1. But there is the dependency for the p7zip unrar
plugin in mail/amavisd-new, and I am looking forward to the day when p7zip
will be removed.

I like that solution.

I did, and on amd64 I get an assembly error compiling C/LzFind.c. Log
