groff needs >=texinfo-4.0 as a dependency because it uses it to compile the docs. you can verify this from doc/Makefile.in. texi2dvi is a part of texinfo, and without it groff will fail. however, this omission does not affect installing from scratch (1.2 or 1.4) or upgrading from 1.2 to 1.4 following the upgrade to 1.4 guide. but it did fail when i tried "emerge -u" on a gentoo 1.2 with an old texinfo-2.95 (not upgrading to 1.4 at all.) however, groff is rather important, and i'd rather keep it status quo as it is until 1.4 ships. but the changes are simple, just add >=sys-apps/texinfo-4.0 to DEPEND. this should always be satisfied with new installations because texinfo is also a DEPENDency of sys-devel/gcc.
It should be ok as gcc already pulls in texinfo. Ill do a bootstrap and verify.
Fixed in cvs, thanks.
