It _is_ opensource and the SVN repository is located on sourceforge. I do not commit any change though until I am OK with the current situation. The SVN contains sort of baselines of the current code I am OK with.
How about that:
1) I promise I would commit every single change to the sourceforge SVN. Even a single new comment line.
2) I charge you modest ammount of BTC for answering any question related to build configuration and compilation.
You see, my spare time is rather limited and it is going to be even more limited if I have to answer questions about building a code I still consider experimental. Debugging build issues and solving people's build problems takes up my time I can use for improving the software. I am giving you a compiled binary and spare you from installing the right prerequisites and do the necessary things for a successful build. Some of the prerequisites are not even present in the distro's repositories, so (for example on Slackware) you'd have to build them from source.
Then again it all boils down to the following: since you value opensource that much and need transparent, real-time access to the code. On the other hand (eh) I am the only one working on that project and my time is too limited to resolve problems of users that want to build experimental code. Are you willing to pay for that support? I'd think no.
