Couple of corrections - neither pypy nor starkiller are compilers. Starkiller isn't available yet and *may* be helpful in building compilers. Pyrex is an alternative language - a python/C hybrid that can be compiled.
If you want to release an application then innosetup, starkit, and upx might help - but they're not python related. You will need something like py2exe, cx_freeze, or mcmillan installer. (Which are specific to python - py2exe seems to be the more mature tool). Alternatively you could consider 'Movable Python' - a frozen distribution of python that doesn't need isntalling.
