Opensuse 11.4 (which is current release) use openssl 1.0.0 and also lacks of md2. From openssl version >1.0.0 MD2 is disabled by default. However Fedora 15, Centos 6 have openssl 1.0.0 versions with md2 enabled.

Dev branch on github contains problematic md2 support, but in  R14B04 release this feature is removed.
