There are a couple of solutions here.

1.  Use the full executable path rather than rely on $PATH

2.  Set up your path environment variable so it is picked up by
non-shell processes.  When you run the Mathematica kernel from within
the Mathematica notebook front end, the kernel inherits its environment
from the front end.  The front end (when you launch it from the Dock or
Finder) inherits its environment from loginwindow process, which is not
a shell and does not read shell resource files on startup.  The way to
get all processes (both shell & non-shell) to inherit an environment
variable is to set up the variable in the ~/.MacOSX/environment.plist
file, as described here
