Re: cmake error on Ubuntu 13.10

[David Chisnall]

Hi Patryk,

It appears that you have an incomplete LLVM installation.  As per the INSTALL 
file, adding -DLLVM_OPTS=OFF to the cmake command line will disable the attempt 
to build the LLVM optimisation passes.  I may make this the default for 1.7.1, 
since a few people have had problems with it.
