What says "objdump -x __m2crypto.so"?
I get:
Dynamic Section:
NEEDED libssl.so.3
NEEDED libcrypto.so.3
I've recently upgraded my FreeBSD world to 4.10-RELEASE. These .so's are
the system-built ones.
$ which openssl
/usr/bin/openssl
$ /usr/bin/openssl version

Perhaps you have more than 1 installation of OpenSSL on your system, and
are somehow linking with the old one?
Python and SWIG builds aren't relevant in this case.
(BTW, FreeBSD 4.3 is _really_ ancient.)
HTH. Cheers.
