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.

oh sorry. I have misunderstood Xcode-4.1 default compiler. I set "default_compiler gcc-4.2" in macports.conf.

I tried to build with configure.compiler=llvm-gcc-4.2

this error is same to configure.compiler=gcc-4.2 and configure.compiler=macports-clang-3.3.

Xcode 4.1 is not supported.

[h.rayflood@…]

llvm/clang 3.4 build check.

xcode	llvm-gcc-4.2	clang	clang version	macports default
4.6.3	OK	OK	4.2	clang
4.5.2	OK	OK	4.2	clang
4.4.1	OK	OK	4.0	clang
4.3.3	OK	NG	3.1	clang
4.2.1	NG	NG	3.0	clang
4.1	NG	NG	2.1	llvm-gcc-4.2

clang version in xcode-4.5.2 is 4.2, not 4.1 .
default compiler in xcode-4.3.3 is clang, but it breaks llvm/clang 3.4 .
