If you do not need to use the newest optim package, consider to use optim-1.2.2 
that is  located in C:\octave\Octave-3.8.1\src\optim-1.2.2.tar.gz.  The 
optim-1.2.2 package does not require the parallel package as dependency.

The octave scirpt "build_packages.m" in the C:\octave\Octave-3.8.1\src will be 
help for you.
