OSRM compilation error: /usr/bin/ld: cannot find -lc++. How to overcome?

Question

FreeBSD

Good day!
I'm trying to build OSRM under FreeBSD 9.3, but it still doesn't work. Ultimately, when I do cmake, the following happens:

/usr/bin/clang++ -stdlib=libc++ -I/usr/local/include/c++/v1/tr1
  -L/usr/local/lib/c++ -v
  CMakeFiles/cmTryCompileExec2359982921.dir/testCXXCompiler.cxx.o -o
  cmTryCompileExec2359982921

   "/usr/bin/ld" --eh-frame-hdr -dynamic-linker /libexec/ld-elf.so.1 --hash-style=both --enable-new-dtags -o cmTryCompileExec2359982921 /usr/lib/crt1.o /usr/lib/crti.o /usr/lib/crtbegin.o -L/usr/local/lib/c++ -L/usr/lib CMakeFiles/cmTryCompileExec2359982921.dir/testCXXCompiler.cxx.o -lc++ -lm -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/crtend.o /usr/lib/crtn.o

  /usr/bin/ld: cannot find -lc++

I'm trying to compile like this:

cmake .. -DCMAKE_CXX_COMPILER_ID=Clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_FLAGS='-stdlib=libc++ -I/usr/local/include/c++/v1/tr1 -L/usr/local/lib/c++ -v'
