I'm not sure -- it could be that it is installed but not being found
when you try to run it.

It would be helpful to have more details.  Like, when you say you
successfully installed PGPLOT, Ifeffit, and the horae suite, where did
these get installed to?

When you try to run these, what are you doing (typing a command in a
terminal, clicking on a file?), and what messages do you see.

iXAFS is an App that bundles together the horae and ifeffit programs.
It should not be necessary for running Ifeffit if you install it
yourself, but looking at the contents of this App (that is,
.....iXAFS.app/Contents/Resources) might give some hints.

If you've really installed PGPLOT and Ifeffit on Mac OS X, I'll bet
you sort of know what you're doing, and that the problem may simply be
in setting an Environmental Variable or something similar.
