-----------------------------+----------------------------------------------
 XCode 4.2's clang fails to build openjade, but llvm-gcc-4.2 works. Also,
 universal builds don't work because libtool doesn't use the magic "-arch
 ..." incantations when invoking the compiler.

 (More generally, i386 builds fail on machines where x86_64 is the default.
 Thus, putting openjade into the muniversal portgroup doesn't fix the
 problems with +universal)

 I've fixed both problems by
 * Setting configure.compiler to llvm-gcc-4.2 if it's set to clang
 * Using reinplace to patch libtool's CC and CXX settings

 Patch for the Portfile is attached.
