I followed all the instructions on the page

http://www.octave.org/wiki/index.php?title=Installing_MacOS_X_Bundle



Specifically:

sudo touch /usr/local/bin/gnuplot

        sudo ln -s /Applications/gnuplot.app/Contents/Resources/bin/gnuplot
/usr/local/bin/gnuplot

        sudo touch /usr/local/bin/octave

        sudo ln -s /Applications/Octave.app/Contents/Resources/bin/octave
/usr/local/bin/octave

But when I typed

        octave

I got "permission denied".

Nevertheless, when I typed

        env

I found that /usr/local/bin *is* in PATH

The next instructions said that I should then e-mail here.
Suggestions?  Thanks.

Please verify you get the following.

        ls -l /Applications/Octave.app/Contents/Resources/bin/octave
        -rwxrwxrwx  1 bpabbott  admin  2968 Apr 21  2011
/Applications/Octave.app/Contents/Resources/bin/octave

It's there, and so is gnuplot.  They both show up, with the correct 
permissions.  One small question, since my unix is rusty:  octave shows 
-rwxrwxrwx and gnuplot shows -rwxrwxrwx@ -- what's the difference?

And I don't understand: if it's -rwxrwxrwx, how can there be "permission 
denied"?

Ok. Now try to run Octave without the link. Just type the part below at the 
shell prompt.

        /Applications/Octave.app/Contents/Resources/bin/octave

OK, that works.

Ok. Now fix the links. First, delete the old ones.

        sudo rm /usr/local/bin/gnuplot
        sudo rm /usr/local/bin/octave

... and then recreate them.

        sudo touch /usr/local/bin/gnuplot

        sudo ln -s /Applications/gnuplot.app/Contents/Resources/bin/gnuplot 
/usr/local/bin/gnuplot

        sudo touch /usr/local/bin/octave

        sudo ln -s /Applications/Octave.app/Contents/Resources/bin/octave 
/usr/local/bin/octave

I notice that ls -l /usr/local/bin/octave gives -rw-r--r--  Evidently that's 
where the execute permission is denied.  But why is it that way?  Can I merely 
do a chmod?

ok. Try ...

        chmod 755 /usr/local/bin/octave
        chmod 755 /usr/local/bin/gnuplot

Ben

I've added this part to the wiki. Please confirm this works for you.

Nope.  I got

"chmod: Unable to change file mode on /usr/local/bin/octave: Operation not permitted"

"Unable to change file mode on /usr/local/bin/gnuplot: Operation not permitted"
