Those are, as you can see from the messages, warnings, not errors.  They
won't cause the compilation to fail, by themselves.

As Mason suggests, this is because by default (and for good security
reasons) your current directory is not on the list of places the system
will look for programs to run.

So if you want to run a program in your working directory you should
prefix it with the path (either absolute or relative) to your current
directory.  Typically that means, as the documentation that Mason quotes
suggests, you would run "./REAP", not "REAP".


Also as Mason suggests, none of this has anything to do with make. You'd
be better served locating mailing lists or forums discussing the REAP
package and asking these questions there.

Cheers!
