One (not at all easy) solution is to build fritizing from source. Having done so, I can safely say donating and downloading the built product is much better, but it is possible to do it entirely for free (except for a lot of time.) There are build instructions available here (with an update to build 0.9.4 as well):
they assume you are reasonably familiar with software development and tool installation though. The Qt download alone typically takes me around 8 hours (often multiple times as I screw something up and have to start again.) You want the Qt open source version (which is free.)
