Well, I tried LLVM/CLANG, but Cmake of the sources fairly fails many

Yes, it is currently not supported. I am not sure if there are serious
attempts to add it.
Using clang++ requisites the usage of the
new libc++ (CXXFLAGS+= -stdlib=libc++). But this fails with this error:
...
/usr/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src/parser/parser.h:118:15:
error: no viable conversion from 'std::__1::basic_istream<char>' to
'const bool'
const bool ok = in.get(c);
^ ~~~~~~~~~
This is a bug in FreeOCL. The istream::get() function returns an
istream reference, which can't be cast directly to bool. However, there
is a negation operator defined for istream, so the line can be changed
to:
const bool ok = !!in.get(c);
I have attached a patch for the port as I have built it here with clang.
I didn't add the dependency on atomic_ops yet, but it should be fairly
trivial.
Note I also needed a fix for Mk/bsd.cmake.mk, otherwise the required
${CPPFLAGS} would not be passed along to CMake, and then the build would
still fail to find the atomic_ops headers in /usr/local/include.
