llvm dev - Feb 2008 - [LLVMdev] llvm 2.2 build problems

I'm getting an error when trying to build llvm 2.2's tblgen:

llvm[2]: Linking Release executable tblgen (without symbols)
/usr/bin/ld: Undefined symbols:
llvm::MemoryBuffer::getFileOrSTDIN(char const*, unsigned int,
std::basic_string<char, std::char_traits<char>,
std::allocator<char>
>*, long long)
llvm::cl::ParseCommandLineOptions(int, char**, char const*)

It's being run with this to configure: "./configure
--prefix=/opt/local --enable-optimized --enable-jit"

and this to build: "make tools-only"

What am I doing wrong? I'm on an intel macbook pro running 10.4.11.

Finally, here's the full build log:

Thanks!

It turns out my problem was that I still had llvm-2.0 installed, and
I'm guessing the build script was  finding 2.0's libLLVMSupport.a
instead of the one that was just built. I think this happened because
macports (which I'm making the llvm build script for) specifies these
environment variables:

CFLAGS='-O2' CPPFLAGS='-I/opt/local/include'
CXXFLAGS='-O2'
CPP='/usr/bin/cpp-4.0' CXX='/usr/bin/g++-4.0'
F90FLAGS='-O2'
LDFLAGS='-L/opt/local/lib' FCFLAGS='-O2'
OBJC='/usr/bin/gcc-4.0'
INSTALL='/usr/bin/install' OBJCFLAGS='-O2' FFLAGS='-O2'
CC='/usr/bin/gcc-4.0'

If I run the build without CPPFLAGS='-I/opt/local/include' and
LDFLAGS='-L/opt/local/lib' specified it builds fine. Is there anything
that could be changed so that this conflict doesn't happen again?
