Error installing Octave-Forge

I'm using Linpus with the occasional download from the Fedora repos. I've downloaded the Octave package from the latter but I now also need the Octave-Forge package (it has a lot of extensions I need such as the 'regress' function). When I try to download it I get the error:

Code:

[user@localhost Downloads]$ sudo yum install octave-forge
Setting up Install Process

Error: Missing Dependency: ImageMagick = 6.3.5.9-1.fc8 is needed by package ImageMagick-c++
[user@localhost Downloads]$

If I try to load the above package rpm manually I get:

Code:

[user@localhost Downloads]$ sudo rpm -Uvh ImageMagick-6.3.5.9-1.fc8.i386.rpm
Preparing...                ########################################### [100%]
        package ImageMagick-6.3.5.9-2lp (which is newer than ImageMagick-6.3.5.9-1.fc8) is already installed

Is there any way I can force yum to ignore the dependency and install Octave-Forge anyways?
