This problem also affects me. I am using linux, running Pinguy 11.04 (i.e. a tweaked version of Ubuntu 11.04 that does not use Unity or Gnome 3, but Gnome 2, etc.). I get the same error message (i.e. Failed to convert file. Ensure Ghostscript is installed. http://pages.cs.wisc.edu/~ghost) and, on checking in Synaptic, Ghostscript is definitely installed.
I should note: when I first installed Whyteboard, everything worked fine. Then, the broken just stopped allowing me to open up any .pdf files.
