I'm struggling with the same problem. Here's my console script:
/Applications/Inkscape.app/Contents/Resources/script: line 17: open-x11: command not found
2007-06-02 18:50:21.422 open[260] Couldn't open file: /tmp/getdisplay.sh
Here is some copy from a blog review of Inkscape, which looks great btw.

Installation of Inkscape was slightly more complicated. The test system didn’t get built with Apple X11 by default, so I had to install that and reboot before installing Inkscape. Inkscape itself also seemed to have some problems getting started. I had to launch and quit it a couple of times before it finally came up. To be fair, when the application seemed to hang on a subsequent launch, it was clear from the Activity Monitor that X11 was the one having a real problem coming up, so I don’t think Inkscape was at fault. After killing X11 from the command line and rebooting the system, Inkscape came up in only a couple of seconds. I haven't seen this X11 issue since that first attempted launch, so I'm pointing a finger at X11 or a previously-opened X11 application on that machine.
Once up and running, Inkscape was very nearly as fast as a native Mac OS X application (i.e., I think I detected a very minuscule delay but it never bothered me). In fact, if I regularly used the Macintosh, I’d have no problems at all working with Inkscape on a regular basis. It performed well, was perfectly stable (aside from the X11 issue above that I don’t think is Inkscape’s fault), and never crashed or generated an unexpected error during operation.
New to this debugging thing. Any help will be delighful!
Thanks,
