Comment(by ryandesign@…):

 Why did you add the block:

 {{{
 platform darwin 11 {
         configure.compiler gcc-4.2
 }
 }}}

 In MacPorts 2, compilers are chosen based on Xcode version, not OS
 version. For example, Xcode 3.1/3.2 uses gcc-4.2, Xcode 4.0/4.1 uses llvm-
 gcc-4.2, and Xcode 4.2 uses clang.

 Item 3 of the [http://lists.macosforge.org/pipermail/macports-
 dev/2011-July/015263.html MacPorts on Lion (common issues, fixes, and
 workarounds)] post shows how you should coerce the use of gcc-4.2 instead
 of these other compilers -- if indeed that is the only way this port will
 work. If this port can be made to work with clang instead of llvm-gcc-4.2,
 that is preferable.
