ConvertAll requires the following libraries:

* Python (Version 2.3 or higher)
* PyQt (Version 4.0 or higher - see Riverbank for more information)"
Requiring Qt might be a problem. However, I don't see why a units-conversion
package requires a graphics library like Qt. Indeed, the web site says
"Command line options are available to do conversions without the GUI."

This has been discussed before. I think it has serious licensing
incompatibility issues and also uses java.

Were you able to download and compile the source code for this?
The website (or my computer) was very slow for me, so I gae up looking.
If you did so, what OS did you use? Do you know the license for k3dsurf?
