No, you don't need to compile Lynx with SOCKS (at least for this problem).
Proxy authentication is not supported in Lynx 2.7.1 or earlier.  But it is
in the development code at <URL:http://sol.slcc.edu/lynx/current/> and in
Fote's code in <URL:http://sol.slcc.edu/lynx/fote/patches/>.

That is described in RFC 2068 (there is also a newer draft, <URL:
http://www.w3.org/Protocols/HTTP/1.1/draft-ietf-http-v11-spec-08.txt.gz>,
not in the Internet-Drafts directories).  Basically, you need
`Proxy-Authorization:'.

Some remarks that have nothing to do with authentication:

Does any server do anything with `Accept-encoding: base64' ?

You shouldn't send an empty Accept header field (although most servers
and CGI scripts will ignore it anyway).  I think that may be interpreted
as "no MIME type is acceptable".  Either leave the line completely off,
or use `Accept: */*'.
