- There were no SWC files to use (the 2 provided never worked).
- Building the source required FlexBuilder as well as to understand the project layout.
- Some of the code was not committed, hence the compilation failed in so many ways.
- There were dependencies that were not documented.
I took this as a personal challenge and I can happily report that I made it work. I'd like to describe what I had to do to make it happen in case others go through this problem (as I suspect it's the case based on some of the postings I read on the site).
