[Ryan David Larrowe]

Package: llvm-3.9
Version: 1:3.9.1-8
Followup-For: Bug #845134

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Trying to build mesa from RadeonFeature driver.
   * What exactly did you do (or not do) that was effective (or
     ineffective)? I installed the most recent version of llvm (3.9) and
removed 3.8.
   * What was the outcome of this action? Same problem.
   * What outcome did you expect instead? I expected for configure to find the
right version of llvm.
