 * Ref. your example of Joe user & ports/games/coolgame ...
 * 
 * I'm not advocating it, but fon't forget if we want to, we could extend
 * the ports structure to have 2 md5s, one to to do a quick check of
 * a maximally compressed distfiles/* & 2nd to be checked during a build
 * (possibly as a zcat | md5)

That still doesn't solve the problem.  The point is that we either
need the user to do a znew --best (either by herself or from
bsd.port.mk) or uncompress and check the md5 of the file (using zcat |
md5 like you said) every time the user types "make <something>"
(something being configure, patch, etc.).

The only reasonable solution to this I can think of is to include a
md5 for the original (compressed) tarball and the znew --best version,
and let bsd.port.mk test both of them before complaining.  This should
salvage mirror sites that do a recompression (assuming they are doing
znew --best...if they aren't, to hell to them! ;).
