BGP on Mac OS X?

[cayle.spandon () gmail com]

Does anyone known which open source BGP implementation I can get running on  
Mac OS X Leopard with a minimum of fuss?

This is for experimentation only (not for a production environment) so I am  
not too concerned about scaling and performance.

If any tweaking is needed to get it to compile / run on OS X, a pointer to  
a website with instructions would be highly appreciated.
