Hmmm... yes, the problem was that between 0.9.5 and 0.9.6 the encoding
of OPENSSL_VERSION_NUMBER changed and it seems I adjusted the definition
in ssl_util_ssl.h without recognizing this. I'll use the following now:

-#if SSL_LIBRARY_VERSION < 0x00906100
+#if SSL_LIBRARY_VERSION < 0x00906000

Thanks for the hint.
