Try to add /usr/local/bin to exec-path, not load-path. (load-path is
for *.el and *.elc files, that is Lisp files.)
Or make sure that /usr/local/bin is listed in $PATH at the time when
you start Emacs. (If you start Emacs from a button in the KDE panel,
then it can be difficult to find out whether the directory is in
$PATH, and if it isn't, how to put it there. I never could figure
that out.)
