I'm not sure this is 100% correct... but something like this... might have to edit some of the Path stuff if I have it wrong for your set up... but I'm assuming most of the stuff you've built is off Macports and /opt/local...
do this in a new Terminal session
Code:
export DYLD_FALLBACK_LIBRARY_PATH="/opt/local/lib:/usr/lib:/opt/X11/lib:/usr/X11/lib"
export CC="gcc-4.0"
export CXX="g++-4.0"
export CPPFLAGS="-I/opt/local/include"
export CFLAGS="-arch i386 -m32 -O2 ${CPPFLAGS}"
export CXXFLAGS="$CFLAGS"
export LDFLAGS="-L/opt/local/lib"
then try the configure.... thats similar to how I have the build script in custom Wineskin builds to work.
