problem compiling on gentoo

[Eoksni]

I'm not exactly sure if it's problem of this program or gentoo distribution in general.

Trying to compile gives me /usr/lib/gcc/i686-pc-linux-gnu/4.5.3/../../../../i686-pc-linux-gnu/bin/ld: warning: libLLVM-3.1.so, needed by /usr/lib/llvm/libclang.so, not found (try using -rpath or -rpath-link)
and a bunch of undefined references like so /usr/lib/llvm/libclang.so: undefined reference tollvm::APFloat::APFloat(llvm::fltSemantics const&, unsigned long long)'`

After doing ln -s /usr/lib/llvm/libLLVM-3.1.so /usr/lib/libLLVM-3.1.so all compiled fine.

Linux 3.2.21-gentoo i686,
llvm-3.1-r2 USE="libffi -debug -gold -multitarget -ocaml -test -udis86 -vim-syntax"
clang-3.1-r5 USE="static-analyzer -debug -multitarget -test"
