It might be a problem related to the version of openssl used during the
link of crypto.so.

I can reproduce it on Maverick.
crypto refuses to start with libcrypto.0.9.8 is used, but start correctly
with libcrypto.1.0.0

Either it's a compilation problem (mismatch of the header used for the
compilation and the lib used to link) or a dependency on openssl 1.0.0 has
been introduced in 17.3

You can see the lib dynamique used by crypto.so with
dyldinfo -dylibs $ROOT/lib/crypto-3.4/priv/lib/crypto.so

When it doesn't work, it depends on /usr/lib/libcrypto.0.9.8.dylib

You can change this dependency with ( the example assumes macport to be
installed)
install_name_tool -change /usr/lib/libcrypto.0.9.8.dylib
/opt/local/lib/libcrypto.1.0.0.dylib
$ROOT/lib/crypto-3.4/priv/lib/crypto.so

Hope it helps
