Peter,
Actually, I abandoned using --prefix=%p/lib/llvm-%v because it causes
clang to fail to install the symlink for clang++ with the error...
llvm[4]: ======= Finished Linking Release Executable clang (without symbols)
llvm[4]: Installing Release
/sw/src/fink.build/root-llvm-clang-2.7-1/sw/lib/llvm-2.7/bin/clang
make[4]: *** No rule to make target `/sw/lib/llvm-2.7/bin', needed by

I am attaching a llvm-clang-x86_64.info which uses wrappers for llvm-clang
to find a ld symlink which will use the llvm-2.7 libLTO. This fails to build
with the error above. Any ideas how to fix clang/tools/driver/CMakeLists.txt
to avoid this error?

Description: LLVM Compiler and C Family Frontend
DescDetail: <<
A compilation strategy designed to enable effective program optimization
across the entire lifetime of a program. The Low Level Virtual Machine
supports effective optimization at compile time, link-time (particularly
interprocedural) run-time and offline (i.e., after software is installed),
while remaining transparent to developers and maintaining compatibility
with existing build scripts. Clang is a new C, C++, Objective C and
Objective C++ front-end for the LLVM compiler.
<<
DescPackaging: <<
The previous llvm packaging has been replaced with a llvm-clang package which
provides both llvm and clang in a single build.
The file libLTO.dylib in %p/lib/llvm/lib can be used to replace the libLTO.dylib
in /Developer/usr/lib from Xcode 3.1.2 to enable full LTO support at -O4 in
the compilers of the llvm-gcc42 package. Note that the fink maintainer mode
doesn't understand the @executable_path/../lib/libLTO.dylib syntax in
libLTO.dylib's
otool -L output.
