devil configured without --enable-ILUT still refers to <IL/ilut.h> in devil_cpp_wrapper.hpp

[ilovezfs]

When built without "--enable-ILUT", if you try to compile

#include <IL/devil_cpp_wrapper.hpp>
int main() {
  ilImage image;
  return 0;
}

the following error occurs:

bash-3.2$ /usr/bin/clang++ test.cpp -L/usr/local/Cellar/devil/HEAD/lib -lIL -lILU -o test
In file included from test.cpp:1:
/usr/local/include/IL/devil_cpp_wrapper.hpp:4:10: fatal error: 'IL/ilut.h' file not found
#include <IL/ilut.h>  // Probably only have to #include this one
         ^
1 error generated.

I am able to work around this by applying the following patch for non-ilut builds:

      inreplace "include/IL/devil_cpp_wrapper.hpp",
        "<IL/ilut.h>", "\"ilu.h\""

If I just delete #include <IL/ilut.h>, instead of replacing it with #include "ilut.h", then I get this error instead:
