I found through google.com and then the old Caldera Skunkware site where to get GNU CC, and GNU make, along with other toys like the CD recorder someone else was looking for on here a while ago, it is also on the SCO/Caldera SKunkware website:

Anyways, I used `custom' and got that stuff installed,
but the files for zlib and openSSL come as *.gz!?!?! What the do I use for those, for now I am going to try using WinRAR on my laptop and get them to just *.tar files and go from there. Hopefully there is nothing I need to worry about there.

Never mind I figured out it was gzip, or GNU ZIP, and added nearly every GNU tool on the Skunkware CD that I could find just for good measure on our test box.
Update 4/27/2007
I have GCC and the other stuff needed in the test system now. But, really since I taught myself from the Internet and man pages I am kind of at a loss for what to do now. The zlib stuff seems to be header files, so I am assuming they are not going to get compiled, or so GCC tells me. So should they be included in a "make" for openSSH?
