I finally have the new code in the repository, available for download. If you like working in a development environment, download Qt Creator. A project file is included in the sourcecode, sodacad.pro, to help get you started.
Link to get the code.
Right now the code will not build or compile - there are a number of bugs to work through. There are also several files which need to be changed to reflect a sodacad project rather than librecad. If you are interested in working on this project, just submit two patches to gain commit access.
More info on the Sourceforge project page.
