python: for FreeBSD 10, this may fail

Originally introduced by me based on high hopes and cross-platform
usage.  I was wrong.

A PATH without /usr/local/(s)bin, as advertised by the standard rc(8)
system or service(8) will prevent env(1) from working properly.  We've
had similar fun with configd before.  Maybe we need to take this to FreeBSD.
For now we work around it like every body else, presumably.  :)
