It happened, finally.
Thanks to the efforts of Guerkan Senguen Freecycle is in Debian (unstable branch). You can get it at http://packages.debian.org/freecycle
Now it’s up to me to finish the 0.7 incantation and get finally Freecycle out of the alpha stage. With Qt4 it looks quite promissing as the new Canvas code is much much better now. You can follow the work in progres in the CVS (still not in usable state, but compiles, executes and shows the new rendering code).
