Update to latest libssl for Mountain Lion without MacPorts?
This is how I fixed this, it's based on a couple of threads on Stack Overflow.  

sudo cp /Library/PostgreSQL/9.1/lib/libssl.1.0.0.dylib /usr/lib
sudo cp /Library/PostgreSQL/9.1/lib/libcrypto.1.0.0.dylib /usr/lib
sudo ln -fs /usr/lib/libssl.1.0.0.dylib /usr/lib/libssl.dylib
sudo ln -fs /usr/lib/libcrypto.1.0.0.dylib /usr/lib/libcrypto.dylib


Please take note of what the links you are replacing looked like before you overwrite them so you can put it back the way it was if it causes you grief.  I am not convinced this is a good idea yet, but it's working so far.  I'll edit if it comes back to bite me in the arse.
