I actually ran ./configure w/o any options and got a message from make saying ssl support was disabled...

As a matter of fact, I did run make install. I ended up copying ncat.1 out of your docs/man/ folder to the same spot as 
nmap's man page and it worked after that. 
I ran man -w nmap to find the location. It came back /usr/local/man/man1/nmap.1

We run our authenticated proxy off of port 3128..less restricted. port 8080 requires no auth but more restricted...but 
I know google is not blocked; that's why I chose it as a test. 
I ran the following command to test your proxy-auth syntax:
$ncat --http-proxy myproxy:3128 --proxy-auth user:pass www.google.com 80
result was: Segmentation Fault. 
Did I do something wrong with the syntax?

Good catch. No I did not. I installed libssl-dev through apt-get and ran:
$./configure
$make
$sudo make install
No errors about SSL this time. I copied the new binary to /usr/bin and still no manpage...this is where I figured out 
how to manually copy the man page, as I described above, so that '$man ncat' now works. 

One more thing I will add is that ncat -h does not show the -ssl option though it is listed in the man page. 

Thanks again for your work and hopefully some of this is helpful.
