 I tried configuring with `./configure --prefix=/opt/bootstrap --with-
 applications-dir=/opt/bootstrap/Applications --without-startupitems
 CC='gcc-4.2 -arch ppc -arch ppc64' CXX='g++-4.2 -arch ppc -arch ppc64'` on
 Leopard, and that failed:

 If it cannot work, not a big deal, but if there is a correct way to
 configure it, please let me know.
