Actually, I investigated those additional symbols on my linux box,  
and it appears that they are undefined over there as well. The only  
difference is that the linker on my linux box didn't care...  The  
package works perfectly fine with those symbols undefined, and if you  
read the source, some of them are slated to be removed in future  
versions anyways...

As for environ, it seems that is also entirely unnecessary for  
graphviz Darwin. If you look at the Darwinports patch for  
graphviz-2.6, they've simply removed the functionality to error on  
that symbol being undefined. If you have a solution for this on a  
large-scale, that'd be great, as I agree with you that it would be  
more correct, and perhaps could solve other issues. For graphviz  
though, it seems not to matter.

In any case, I modified the Darwinports patch to be dependent on  
host_os, so that we can patch the source unconditionally in the  
ebuild. If you want to go the route of fixing the undefined symbol  
for environ, please don't hesitate to change my patch. Let me know  
what you decide so that I can contact upstream about the problem.

Thanks!
