Warning Explanation
I think you should have seen the news("odepkg"). It states that it wont load the package automatically. You have to use the pkg load command everytime you need to use or set the option -auto while installing. Use help pkg for more info.

Uninstalling GNU/Octave

If you installed using "make install", you remove by "make uninstall".
The make clean and distclean just clean out the source directories, but
don't remove installed files. Assuming you built both versions of octave
from source using the defaults, you probably installed everything in
/usr/local, so you can probably remove everything with the following:

$ rm -rf /usr/local/bin/octave-****
$ rm -rf /usr/local/share/octave/****
$ rm -rf /usr/local/lib/octave-****
$ rm -rf /usr/local/libexec/octave/****
