  Modified files:
  The approach portsnap uses of "pick a random HTTP mirror" doesn't
  interact very nicely with HTTP proxies: Since proxies do not know
  that all the files on are identical to the
  files with the same names on, said proxies end
  up downloading and storing files in duplicate.
  This commit uses the HTTP_PROXY environment variable, if set, to
  generate a random number seed for use in selecting a mirror.  This
  means that if several systems all have the same HTTP_PROXY value set,
  they will ask the proxy to fetch files from the same mirror (unless
  that mirror fails, in which case all the systems will use the same
  second choice, et cetera).
  Portsnap still doesn't interact very well with "transparent" HTTP
  proxies, but there's nothing I can do about those.
