It's a BSD package, so not that surprising... Mac OS X has it,
but for some reason the SHA256 support is disabled by default:

http://opensource.apple.com/tarballs/libmd/libmd-3.tar.gz

And of course it's statically linked, so it's only /sbin/md5
remaining. (the headers and library install to /usr/local...)


Another package that seems missing from most Linux distros
is mtree, so I made some custom rpm/deb packages for that:

http://svn.macports.org/repository/macports/users/afb/mtree-2.7-5.src.rpm
http://svn.macports.org/repository/macports/users/afb/mtree_2.7-5.dsc

Since MacPorts doesn't actually use Objective-C/Foundation yet,
it was always possible to patch it out or (now) disable it...
But using GNUstep was enough for the old requirements, though
it would probably take some patches for MacPorts.framework ?

--without-objc-runtime --without-objc-foundation
--with-objc-runtime=GNU --with-objc-foundation=GNUstep


But what I meant was using MacPorts to _install software_,
that still doesn't work (any more). Things like "archcheck"
and "make -w" and other such assumptions, break at runtime...
For running a distfiles mirror, it should limp along again ?
