 Hurrms, currently my workstation has Red Hat Enterprise Linux ES 
release 3 (Taroon),

    [bancroft@hilbert w3c-libwww-5.4.0]$ rpm -qa | grep ssl
    openssl-0.9.7a-22.1
    docbook-style-dsssl-1.76-8
    openssl-devel-0.9.7a-22.1
    mod_ssl-2.0.46-25.ent

Have you checked that the openssl-devel package is installed ?

    [bancroft@hilbert w3c-libwww-5.4.0]$ ./configure --with-ssl

All appears well on the configure, however the compile errors out with 
the following

    gcc -DHAVE_CONFIG_H -I. -I. -I../../.. -I/usr/local/include
    -I../../../modules/md5 -I../../../modules/expat/xmlparse

The configure script found a copy of openssl-0.9.7d I had in /usr/local 
!  However, the default version in /usr/include has the same issue, 
namely that HTSSL.c has the #include a bit off.  I made the following 
modification and the compile proceeds as expected,

    /* SSL includes */
    #include <openssl/ssl.h>
    #include <openssl/rand.h>

It would appear that HTSSLReader.c and HTSSLWriter.c have the same issue 
with their includes of ssl.h.  Making the same change there allows the 
compile to complete.

I recall compiling this when the original work was done and do not 
recall having to make this change, so it must be something to do with 
the openssl packaging.

I will try this on a Fedora Core release 2 (Tettnang) machine with

    [vic@pc72:~] rpm -qa | grep ssl
    openssl-devel-0.9.7a-35
    docbook-style-dsssl-1.78-3
    openssl-0.9.7a-35
    mod_ssl-2.0.51-2.9

However, I do not expect it to be different since,

    [vic@pc72:/usr/local/src] rpm -ql openssl-devel | grep ssl.h
    /usr/include/openssl/hmac.h
    /usr/include/openssl/kssl.h
    /usr/include/openssl/ssl.h

Perhaps a patch is warrented.

However, there is a snag with just using the webbot for https after such 
modifications, the requisite make; make install.  Running this command 
on a secure sockets url fails, such as

[bancroft@hilbert w3c-libwww-5.4.0]$ webbot https://sourceforge.net/account/login.php
Can't access resource

Accessed 0 documents in 0.00 seconds (0.00 requests pr sec)
        Did a GET on 0 document(s) and downloaded 0K bytes of document bodies (0.0 bytes/sec)
        Did a HEAD on 0 document(s) with a total of 0K bytes

Using the -v flag for webbot turns up
