I have a project (That works) that I'm trying to compile on my Mac. It uses a variety of things including LLVM, which was the only one I didn't have installed. So I followed the instructions here: http://www.isi.edu/~pedro/Teaching/CSCI565-Spring15/Projects/Project1-LLVM/LLVMInstructions-MacOSX10.9.pdf
This seemed to work, however my makefile required I install LLVM 3.3, while that tutorial is for LLVM 3.5. Now, both before and after installing, when I run make I get the following error:
$ make

clang++ -o ./expr-codegen expr-codegen.tab.cc expr-codegen.lex.cc decaf-stdlib.o `llvm-config-3.3 --cppflags --ldflags --libs core jit native` -ly -ll

As a total newbie to LLVM I have no idea why I can't get the compiler to recognize LLVM and use it. Any help would be appreciated. Thanks.
