I think that depends entirely on how exactly you plan on using git, for example:

- "python" and "perl" seem to control additional python and perl packages, but
  they are also used by some commit hooks and scripts
- tk is required for the gitk GUI (which is useful for browsing history)
- gpg is required for gpg commit signing
- cvs and subversion are only needed for the "git-cvs" and "git-svn" commands

Otherwise, I'm not entirely sure what you would be missing through such, uh,
"radical" minimalism ;) ; "equery uses git" is your friend for some of the
other flags, e.g., curl is required for http[s]:// repository URLs.
