How to change the default version of the llvm tools?

[blastmaster]

Hi everyone,

I've a question especially concerning the clang tools.
I've running a debian sid distribution and have different versions of
clang installed see the dpkg-query listing below.
Now I've the problem that my OS uses obviously clang-3.8 as default.

$ readlink $(which clang-check)
../lib/llvm-3.8/bin/clang-check

As a result some tools which are just available in newer version are not
in the PATH despite they are installed.
Is there a way to change that or switch between the versions? Or is
there a reason behind which I don't see?


$ dpkg-query -l --load-avail 'clang*'
