Use tr to split $PATH instead of sed
Use tr to split $PATH instead of sed

FreeBSD's sed, and OS X's too, won't take literal newlines in an s/
command, which means that our logic to get the install path doesn't work
and we always rebuild the Jade (and get warnings on stderr).

Therefore, switch to tr, which can handle newlines just fine.
