For some reason we do need the LD_LIBRARY_PATH even for make. I forget which step it is, but there is one that fails without this. I agree, it'd be better not to have to do this. Hopefully we can do this when we figure out the right way to pull V8 into the system.

	8 You'll probably need to adjust your `LD_LIBRARY_PATH` to point to where your v8

	9 libraries are.

	10

	11 You'll need to build v8 as a shared library. Build it like this:

	12

	13 ```

	14 make -j48 native component=shared_library
