Vim on Leopard (each OS < 10.6)

[Eckard Brauer]

Just set up my Powerbook with a virgin Leopard OS, installed fresh
Macports and tried to compile Vim. That does install all the
dependencies fine, but has errors compiling vim itself:

:info:build In file included from vim.h:283,
:info:build                  from alloc.c:14:
:info:build os_mac.h:273:32: error: dispatch/dispatch.h: No such file or directory

As this file seems to be included with only Xcode versions for OS'
starting with Snow Leopard, I suspect that installing MacOSX10.6.sdk
could solve that - if it installs on 10.5 at all (still runing through
the deps, so I can't tell for now). In case it does, it should maybe
belong to the dependencies of vim, in case it doesn't, there seems to
be no way to install a recent vim version, so is there any previous
version one can install?
