So I ended up doing something like this on #4386, but I'd be really
curious if there's a better way. In particular, here's what I did:
find_phc = os.popen2('which phc')[1].readlines()
if find_phc == []:
raise ValueError, "phc not found"
The popen2 returns a pair of file handles, the first wrapping stdin,
and the second wrapping stdout. (In fact, looking at this, I realize
that I forgot to close these file handles ... patch up at #4428.)
So is there a better way to search your path for an executable in Python?
