[llvm-dev] Building a program with LLVM on Unix

[Russell Wallace via llvm-dev]

When you say 'configuring and installing an appropriate version of LLVM and
its libraries yourself' - that is indeed what I did on my own machine
(Ubuntu 14.04 apt-get thinks 3.4 is latest, so I'm currently building 3.8
from source) - but how would you recommend doing this on a user's machine?
