So, my solution was to build and include my own libcrypto.0.9.8.dylib and
libssl.0.9.8.dylib. This takes a bit more than a simple config && make as
you have to go into one of the Makefiles and update the library search paths
sent to the linker for the sharedlib build-step BUT:

overall, the application works crash-free now with curl, openssl, and
threads. woo!

thanks to all for pointing me in the right direction.

mark.
