Done.  ruby-1.8.7-p352 with separate ruby-tcltk package is ready.

See the "spec" noted above, but if ngroups is correctly sized, all
groups to which the given user belongs are returned AND the given group
even if the user is not a member thereof.

That makes sense, given that on BSD[1], initgroups(3) is basically
getgrouplist() followed by setgroups().  The primary difference will be
adding the given group if not a member and assuring proper size of
ngroups.  (Yes, I did look into this myself once upon a time.)
