The fact that you needed to addpath manually already suggests that
there's something wrong. You should have "pkg load" and "unload" take
care of the paths for you. What packages have you installed? What does
"pkg list" shows? Remove (or comment out) that addpath line from your
octaverc, start Octave again, and load the signal package only. Do you
have a problem accessing its functions? Also, I know Debian has a file
in /etc/octave.conf that used to mess up with my pkg. Does Fedora also
has one (maybe in some other place)?

For packages you want to load automatically at startup, the
recommended way is to add a "pkg load pkgname" in your .octaverc file.
You can have multiple in one line "pkg load pkgname1 pkgnam2
pkgname3". For packages ones you don't want to load automatically, do
nothing, and load them only whenever you need them.

Paths for packages are not be saved in .octaverc. pkg does not touches
your .octaverc file. It has another file with the list of packages and
their paths and adds and removes them to your search path when you
load and unload a package.
