Ok, I assumed that you had /usr/pkg/bin at the front.
Unfortunately I don't have a DFly box with Linux_base
installed, so I thought it works the same as on on my
FreeBSD machine, where the Linux bash has "which" as a
function that comes from this file:
This function uses bash's builtin "type" command to
implement the "which" command. Since this is executed
by the linux bash, it finds /bin/bash if /bin is at the
front of the $PATH, of course. That's why I made the
initial assumption that you had /usr/pkg/bin at the
front instead. :-)
Of course, if your linux bash executes /usr/bin/which
(which is a BSD binary, not a script), then it will not
look at /compat/linux at all when looking for a program.
If it was a shell script, things would be different.
