Thanks to the work from Daniel Narvaez we have a new tool for building Sugar from the sources: [http://sugarlabs.org/~dnarvaez/sugar-docs/index.html sugar-build]. This has replaced our previous tool [http://wiki.sugarlabs.org/go/Development_Team/Jhbuild sugar-jhbuild]. sugar-build does currently support several distributions out of the box Fedora 17, Fedora 18, Ubuntu 12.10, Debian Wheezy in both 32-bit and 64-bit. And adding a new distributions is possible and [http://sugarlabs.org/~dnarvaez/sugar-docs/build.html#adding-a-new-distribution documented] as well. Try it out, you will love the ease and reliability of this new tool.
