[gentoo-alt] Bootstrapping failed: llvm-c/lto.h file not found

[Philip]

Hi,

I have a problem with bootstrapping on OS X 10.11.5 with Command Line Tools 7.3.1.
bootstrap-prefix.sh fails during the stage 2 when it tries to emerge sys-devel/binutils-apple-7.2:

clang++ -m64 -march=native -O2 -pipe -Wno-invalid-offsetof -std=c++0x -stdlib=libc++ -I/gentoo/tmp/usr/include -DNDEBUG -DSUPPORT_SNAPSHOTS -Iinclude -Iabstraction -Ild -Ild/parsers -Iother -I.  -c -o ld/ld.o ld/ld.cpp
clang++ -m64 -march=native -O2 -pipe -Wno-invalid-offsetof -std=c++0x -stdlib=libc++ -I/gentoo/tmp/usr/include -DNDEBUG -DSUPPORT_SNAPSHOTS -Iinclude -Iabstraction -Ild -Ild/parsers -Iother -I.  -c -o ld/passes/bitcode_bundle.o ld/passes/bitcode_bundle.cpp
ld/passes/bitcode_bundle.cpp:36:10: fatal error: 'llvm-c/lto.h' file not found
#include "llvm-c/lto.h"
         ^
1 error generated.
make: *** [ld/passes/bitcode_bundle.o] Error 1
make: *** Waiting for unfinished jobs....
  * ERROR: sys-devel/binutils-apple-7.2::gentoo_prefix failed (compile phase):

Any idea what I am doing wrong?

Thanks, Philip
