Comment(by ongrie@…):

 Replying to [comment:11 ryandesign@…]:
 > Several other ports use the same programming to force the use of
 gcc-4.2; these might also fail because of your rogue gcc-4.2/gcc-4.0
 compilers, so I recommend you remove them. If you need the Apple versions
 of gcc while using Xcode 4.2, consider using the compilers installed by
 the apple-gcc42/apple-gcc40 ports. These should be slightly newer versions
 that should work on Lion.

 OK thanks! I'm now building apple-gcc42 and try it again. One more
 question, how should I remove my "rough gcc4.2" compiles safely?
