Linking to libcrypto

I need to use some MD5 functions in my application. I am linking against libcrypto for the MD5 functions. When I build on Panther, it runs on Panther fine. When I build with the "development" settings, it also runs on Jaguar, so long as I've copied libcrypto to my project folder and run it through "install_name_tool -id @executable_path ...". If I don't copy and frob libcrypto, my application tries to link against /usr/lib/libcrypto.0.9.7.dylib. this is contrary to behavior I've seen on any other Unix. It should be linking against the generic version of the library -- the symlink with a less specific version in its filename -- rather than the exact version on the current OS. When I copy the application to a Jaguar box for testing, it fails, looking for /usr/lib/libcrypto.0.9.7.dylib, rather than finding /usr/lib/libcrypto.0.9.dylib (or better yet, /usr/lib/libcrypto.dylib). The install_name_tool trick doesn't work, either. My expectation is that both will link to /usr/lib/libcrypto.dylib. Or failing that, use the version in the Frameworks directory of the application. Having to copy a system library into the application's local libraries seems like an awful hack, anyway.

How does one get linking to actually work on OSX such that applications are portable between versions?
