Hmm. Too bad it didn't fix all the problems! I would guess you are hitting some strange bug in the automatic pre-compilation mechanism recently merged into Julia master.
Disclaimer: this is all unfounded speculation, but here are my thoughts on what might be happening. It seems that until most (all?) packages choose to opt-in to precompiling (by putting `__precompile()__` before the declaration of their module) we might have issues loading packages with a large number of dependencies (like QuantEcon) where some have opted in an others haven't.
