Confirmed, I get the same thing on Snow Leopard. After some Googling it seems that you simply can't use libcrypto.0.9.7 on Snow Leopard. You must use a later version. And this project hardcodes the use of libcrypto.0.9.7. It should be changed to use the MacPorts version in all cases, if possible.
Note, however, that your output above shows that you have things in /usr/local, which is not supported, because software installed there can interfere with MacPorts. You should move or remove /usr/local to avoid future problems.
