I just want to ship libclang + deps. Which, for instance, on my system is just 
around 50M ("unoptimized", from distro packages).

# ldd libKDevClangPrivate.so | grep -i llvm                                    
        libclang-3.7.so.1 => /usr/lib/llvm-3.7/lib/libclang-3.7.so.1 
(0x00007f01ae2b3000)
        libLLVM-3.7.so.1 => /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1 
(0x00007f01a6260000)

# ll -Lh ...
-rw-r--r-- 1 root root 14M Mar  7 12:59
  /usr/lib/llvm-3.7/lib/libclang-3.7.so.1
-rw-r--r-- 1 root root 36M Mar  7 13:00 
  /usr/lib/x86_64-linux-gnu/libLLVM-3.7.so.1

On Windows, it's even less, because everything is linked statically into one 
single DLL, unused symbols are stripped: libclang.dll (~ 20 MB)

Note: I don't want to ship the Clang toolchain, I just want to ship what's 
required for the KDevelop parser. Huge difference.

So, you agree it's easier to just ship our own version...?

Note that compared to other IDEs, KDevelop still has a *super* low image size. 
KDevelop is around ~ 300 MB unpacked on Windows, including all deps such as 
Qt5/KF5/Clang/LLVM. Compare that to other IDEs.

There's still a high optimization possibility by stripping some or packing all 
icons.

Unrelated, sorry.

Just libclang is needed. Not a full LLVM+Clang install.

Sorry, I'm not really familiar with MacPorts.

Cheers,
