           Summary: release management; llvm-config has absolute paths
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nicholas at mxc.ca

I did an LLVM build with --prefix=/home/nicholas/2.6/llvm-2.6-install. The
resulting bin/llvm-config binary has these lines:
  my $PREFIX              = q{/home/nicholas/2.6/llvm-2.6-install};
  my $LLVM_SRC_ROOT       = q{/home/nicholas/2.6/llvm-2.6};
  my $LLVM_OBJ_ROOT       = q{/home/nicholas/2.6/llvm-2.6};
and if I were to also have built with llvm-gcc, these:
  my $LLVMGCCDIR          = q{/home/nicholas/llvm-gcc/install};
  my $LLVMGCC             = q{/usr/local/bin/llvm-gcc};
  my $LLVMGXX             = q{/usr/local/bin/llvm-g++};

There's nothing wrong with this until you start thinking about a release. We
don't know where people are going to put their llvm install trees. Can we
mandate that they unpack into /usr/local/? Should we have a special "relative
to $0" mode for releases?
