Ok, nice. I tried that 2 or 3 years ago and failed because the  
MacPorts packages weren't really very good at that time.

Oops. I've added a bug to the tracker.

https://www.libavg.de/wiki/index.php/Libavg_on_Mac_OS_X is up-to-date,  
though :-).

Yes, the bootstrap script is meant for installing without external  
packages. The toolchain is included in http://www.libavg.de/macdependencies.tar.bz2 
.

Thanks :-). I've comitted that.

I think we need a line in avgrc for this...

Please use svn diff the next time. Figuring out what baseline you used  
becomes hard otherwise.
