Many ports have had to add -L{$prefix}/lib to the LDFLAGS and -I$

I would think the same should apply to CPPFLAGS and/or CXXFLAGS,
not that I have yet understood why there are two variables for C++
code or what the difference is between them.
I am working on a new mechanism that would allow that (and also fix
some issues with universal variant, the fact that most ports in
MacPorts are compiled with -O0, etc.)
Yes, I should have mentioned the -O0 problem too. And there's a
related problem with the universal variant, that "-isysroot /
Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc" is only added to
the CFLAGS, not the CPPFLAGS and/or CXXFLAGS, and that this should be
remedied.
What is this new mechanism you're working on? I would have thought
that MacPorts already somewhere defines what default environment
variables to use, and that the -L and -I options could simply be
added to it, without requiring any major reworking.
