In fact, the package binaries should not even be appended to
EXEC-PATH. If a package wants a binary, it should know what directory
to look in, rather than looking in a semi-random global path which
might actually include another binary with the same name in front of
it. mmencode is a prominent example, where we've avoided problems in
the past merely by virtue of the fact that Metamail hasn't changed
recently.
I intend to hack this in the next Great Path Overhaul which I'll
get
to once 21.0 is out.
Fair enough. The $PATH of least of resistance is to add the
directories in 21.0 but not 21.2 and use a different solution there
when you work it out.
