No, bison should not be required. You have found a bug in our Makefiles.
> With bison installed, the build gets past TableGen but breaks later:
> gmake: Entering directory `/usr/home/emil/objdir/tools/opt'
> /usr/home/emil/llvm-2.0/Makefile.rules:1021: *** multiple target patterns. Stop.
> This is because $(ProjLibsPaths) contains:
> "/usr/home/emil/objdir/Release/bin/llvm-config llvm-config: Perl not
> found so llvm-config could not be generated"
> Should configure also error out if perl isn't installed?
Yes. Reid has changed this so that perl is now required.
Thanks so much for reporting these!
