Comment:

 The error in the log is:

 {{{
 :info:build Undefined symbols for architecture x86_64:
 :info:build   "llvm::LoopBase<llvm::BasicBlock, llvm::Loop>::~LoopBase()",
 referenced from:
 :info:build       llvm::(anonymous
 namespace)::ScalarEvolutionsTest_SCEVMultiplyAddRecs_Test::TestBody() in
 ScalarEvolutionTest.o
 :info:build ld: symbol(s) not found for architecture x86_64
 }}}

 But why are you specifying `configure.compiler=clang`? You should let
 MacPorts pick the compiler it wants to. In this case (since you have Xcode
 4.1) that would be llvm-gcc-4.2. You should really consider upgrading to
 Xcode 4.6.3.
