net-mail/dot-forward currently has a dependency on sys-apps/groff that it doesn't really need. The current ebuild calls "make it" The Makefile dependencies for "it" are "prog" and "man". "prog" compiles the program "man" generates a dot-forward.0 plain-text file out of a dot-forward.1 manpage and requires nroff. dot-forward.1 is distributed with the tarball. The dot-forward.0 file is discarded on install. Therefore, if the ebuild is modified to call "make prog" instead of "make it" the groff dependency would go away without any side effects.
Added -r2 to portage, can you check it, please?
Marked stable.
