You will be much better off, including with other ports of GNU/Unix
software, if you just put them all on PATH.  I see no good reason for
keeping them in a directory that is not on PATH.  Not every program
called by Emacs has a user option that allows you to spell out its
full absolute file name.

(FWIW, I have a single `bin' directory into which I put _all_ the
programs and DLLs that do not come with Windows out of the box, and
that directory is very near the beginning of PATH.  I have yet to see
a single use case where this arrangement failed me, be it in Emacs or
elsewhere.  So this is what I recommend to others, unless there are
_very_ good reasons not to use this setup.)
