I'm seeing a lot of build failures recently:
(1) on x86-64 linux, gcc 4.1.2:
...
llvm[3]: Compiling Hello.cpp for Debug build (PIC)
llvm[3]: Linking Debug Loadable Module LLVMHello.so
/usr/bin/ld: .../llvm/build/llvm/lib/Transforms/Hello/Debug/.libs/Hello.o: relocation R_X86_64_PC32 against `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::~basic_string()@@GLIBCXX_3.4' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
...
(2) on alpha, gcc 4.2.4. The "unknown component name: alphacodegen"
didn't use to occur.
...

llvm-config: unknown component name: alphacodegen

(lots more of these)
(3) similar problem on sparc64, gcc 4.3.1:
...
make[2]: Leaving directory `.../llvm/build/llvm/tools/llvm-link'
llvm-config: unknown component name: sparccodegen
make[2]: Entering directory `.../llvm/build/llvm/tools/lli'

Not sure when these started failing - sometime within
the last two weeks.
Ciao,
