Shibboleth installation

[Velotiaray]

Hi!

I would like to install a shibboleth service provider on my freebsd 6.1. 
Unfortunately it seems that there is no ports available (*.tbz) and the 
compilation is a hard ... :(
I'd like to know if  someone has already installed such a shibboleth 
(with opensaml). My problem is my C compiler refuses to compile :( When 
I try to compile a program, it says (./configure) "Cannot run C compiled 
programs".

If somebody has an idea, please!

Velotiaray.
