Since you provide very little additional information, a wild guess:
OpenSSL 1.0.1e support TLSv1.2, while 0.9.8 only TLSv1.
With TLSv1.2 SHA-2 digests may have been negotiated, and if
your RSA key size is too small (e.g. 512-bit RSA keys, which
you should not use by the way, too easy to crack) the key may
be too small to encrypt a SHA-384 digest.
If you capture the handshake and decode it with wireshark, you'll have
a lot more detail available. And do make sure your key sizes are all
reasonable.
