FWIW, an updated src.rpm based on realcrypt 4.3 is available at:
http://home.arcor.de/doktor5000/RPMS/realcrypt-5.1a-2mud2008.1.i586.rpm
Working fine on 2008.1, the only issue it has as described in
https://qa.mandriva.com/show_bug.cgi?id=41125
that special characters and umlauts in the README.urpmi
are not displayed correctly.
