Hi Thomas,

Without more details it is difficult to be sure what the real problem
is, but my guess is that you simply need to link against another of the
libwww sub-libraries.  I suspect that ultimately this is because you're
not giving the correct options to all the "configure" commands.

If you've built libwww correctly using --with-ssl, then you can type
either of these commands to find your missing symbols.

  $ nm -g ./Library/src/SSL/.libs/libwwwssl.a | grep " T "
  $ nm -D ./Library/src/SSL/.libs/libwwwssl.so | grep " T "

(These commands work for me on my GNU/Linux system.)

If that gives you the answer you need, then simply add this library to
the link line that you were using, e.g. manually, with:

   -L../path/to/libwww/Library/src/SSL/.libs/ -lwwwssl

or, better still, using automake, by ensuring "@LIBWWWSSL@" is found on
your program's _LDADD line in its Makefile.am
