libradius, EAP, Message-Authenticator - patches

Hi,

I had to modify libradius to be able to proxy EAP requests between Mpd and
the RADIUS server.
If the EAP-Message attribute is present in a request, then also the
Message-Authenticator must be present, othwerwise the RADIUS server drops
the request. (The Message-Authenticator is an HMAC-MD5 Hash of the whole
request packet).
I'm using openssl for calculating the HMAC, and got rid of -lmd, but it
looks like, that this causes problems when doing a buildworld, because ssl
is build after libradius (output from 4-Stable):

It looks like we have to change the order of the _prebuild_libs in
src/Makefile.inc, but I'm not familiar with the build system, and I'm
not aware of the side-effects of this change.

The patches can be found here:
http://www.bretterklieber.com/freebsd/libradius.diff (4-Stable)
http://www.bretterklieber.com/freebsd/libradius5.diff (5-current)

It would be great, if somone could give me some advices how to solve the
problems above,

thanx,
bye,
