That last point is important which I forgot to mention, especially in operating systems that have '.' first in PATH. I notice the difference anecdotally without measuring it, but I don't know if that is a conception bias because I know env should be slower. The best way would be an autoconf script in your package and an install run that finds and verifies the local framework. I have to admit that I have never done this though. I have a few Python scripts with decent distribution and just rely on the direct path (and a batch file for win32)
