Correct guess:

~/pyrun$ dpkg -l | grep libssl
ii  libssl-dev                           0.9.8o-4squeeze7                     SSL development libraries, header files and documentation
ii  libssl0.9.8                          0.9.8o-4squeeze7                     SSL shared libraries

So... is the best way to fix this to get the source for that library, 
build in a separate library and then do the steps below?

I don't see "Runtime" in the stuff downloaded by install-pyrun, and while 
the web page [1] mentions a source tarball, I cannot find a link to 
download a source archive for pyrun.  Am I missing it on that page?

Thanks for the guidance!
