Need help installing Comix Cursors from source

[MountainX]

I'm using Ubuntu 10.10 and I want to install Comix Cursors.
The repo has version 0.6.1. I want the latest version 0.7.3.

I have both ImageMagick and librsvg installed.

The next step in the install process is to run ./bin/build-cursors. When I do that, I get a bunch of output like this. At first I thought it was an imagemagick problem, so I used synaptic to reinstall that. But I still get the same errors. Here's a random sample:

mogrify: unable to open image `build/s-resize.RightHanded.48.#000000.0.7.shadow.png':  @ error/blob.c/OpenBlob/2498.
