Can't install dk-milter

[jabailo]

I was trying to install the dk-milter rpm described in this article:

http://www.howtoforge.com/how-to-implement-domainkeys-in-postfix-using-dk-milter-centos5.1

However, when installing it says:

kanaadmin@susemail:~> rpm -Uvh http://www.topdog-software.com/oss/dk-milter/dk-milter-0.6.0-1.i386.rpm
Retrieving http://www.topdog-software.com/oss/dk-milter/dk-milter-0.6.0-1.i386.rpm
error: Failed dependencies:
libcrypto.so.6 is needed by dk-milter-0.6.0-1.i386
libssl.so.6 is needed by dk-milter-0.6.0-1.i386

I'm running the dkim-milter and it installed version 0.9 of these libraries.
