So let's be a little more specific.  You are saying that it's 
/usr/local/include and /usr/local/lib that are the problem, not 
/usr/local/bin, right?  Otherwise you're saying that, for example, 
MacPorts is incompatible with BBEdit (which puts symlinks in 
/usr/local/bin).  Very few "ordinary" installers install into 
/usr/local/include or /usr/local/lib, but a number install to 
/usr/local/bin.  I don't see that as a major problem.
