Fix out-ouf-source build for runtime as well. To build out-of-source, follow these steps: # [[Insert LLVM build instructions here]] mkdir my_build_dir cd my_build_dir svn co http://svn.dsource.org/projects/tango/trunk tango ccmake <PATH_TO_SOURCE> # (Regular ccmake stuff, press 'c' a few times followed by 'g') make make runtime # add `PWD`/bin to PATH closes #213
