pkg installation help

I'm using centos 6.7

I installed octave from source using the following method.

I found this file here for the spec file

I edited it a little and am attaching the result of my editing

I then ran rpmbuild -ba octave-4.0.0.spec

then I installed all the rpms that came with it.

After that I wanted to run ode45 and found I needed to install odepkg to do so.

I found this page describing how to install and check packages installed

so I ran
pkg install -forge <packagename>
odepkg     and

> pkg list
Package Name       | Version | Installation directory
          general  |   2.0.0 | /usr/share/octave/packages/general-2.0.0
   linear-algebra  |   2.2.2 | /usr/share/octave/packages/linear-algebra-2.2.2
missing-functions *|   1.0.2 | /usr/share/octave/packages/missing-functions-1.0.2
        multicore *|  0.2.15 | /usr/share/octave/packages/multicore-0.2.15
           odebvp *|   1.0.6 | /usr/share/octave/packages/odebvp-1.0.6
           odepkg  |   0.8.5 | /usr/share/octave/packages/odepkg-0.8.5

shows the installed packages
now when I try following an example of using ode45 from here

I can build the function dr_gravi
I can build the initialVector, StartT and StopT
but when I get here

[T,Result] = ode45( @dr_gravi,[StartT, StopT], initialVector)

I get

octave:9> StopT = 0.7 %s
StopT =  0.70000
octave:10> [T,Result] = ode45( @dr_gravi,[StartT, StopT], initialVector)
warning: Octave provides lsode for solving differential equations.  For more
information try `help lsode'.  Matlab-compatible ODE functions are
provided by the odepkg package.  See

Please read `' to learn how you can
contribute missing functionality.
warning: called from
    __unimplemented__ at line 524 column 5
error: 'ode45' undefined near line 1 column 13

As if it doesn't understand ode45 Do I need to do something to get it to load these functions?
