Ok, I've had a look at the problem. Your *.log seems to be ok. However, what I 
can't find in the odepkg-0.4.1.tar.gz files is the PKG_ADD file. So I think the 
solver functions are not loaded after the installation what seems to be your 
problem.

I don't have the time to fix this problem for odepkg-0.4.1 but will send you a 
current snapshot odepkg beside any list in a few minutes. This should work for 
you... I read in another email from David that it is planed to build another 
Octave-Forge release soon...
