Ewww!!!

Are you also namespacing the symbols (using C++ namespaces)? If not, this is 
a surefire recipe for symbol conflicts and thus crashes! Anything that ends 
up directly or indirectly (!) linking to 2 different versions of LLVM WILL 
crash at runtime. And with Mesa using LLVM and with lots of stuff linking to 
OpenGL libraries, it is almost impossible to escape linkage with the default 
LLVM.

This is also going to become a maintenance nightmare, for the same reasons 
bundled libraries are one.

Really, there is only one way forward: make your applications work with the 
latest version of LLVM. This explosion of compatibility packages is a recipe 
for a catastrophe.
