Hi,
   I'm pretty sure I'm the wrong person to answer this, but oh

Clang does not have an Ada frontend. It's a "C language"-based
compiler only, e.g. C / C++ / Objective C / Objective C++. LLVM is the
backend, hence the (now deprecated, no longer updated, not available
in LLVM 3.0) LLVM-GCC (GCC 4.2) compiler was needed to compile Ada
source code while targeting the LLVM backend.

DragonEgg is a plugin for GCC proper (specifically, 4.5.x or 4.6.x)
which targets the LLVM backend. Since GCC (only, and not Clang) has an
Ada frontend / compiler, you must use that.
