added a note on openssl and popt dependencies

Dependencies:

  You're going to need openssl (0.9.6 will work fine, possibly 0.9.5 also)

  and popt installed. If you're on Linux, everything will probably work

  fine. If you're not, you're on your own (but let us know how it goes).

If you got the source from cvs:

  Run "./autogen.sh", which will run the various auto* programs and then

  and another to indicate that you're providing no headers). For more

  convenient command-line use, I recommend making a ~/.wgetrc with

  the line

    http_proxy=localhost:9051"

    http_proxy=localhost:9051

  Then you can do things like "wget seul.org" and watch as it downloads

  from the onion routing network.
