Also, make sure you have installed xulrunner-dev or the equivalent.
If that doesn't work either, then the problem is that unstable has a too new

Mozilla people tend to change the interfaces at will which tends to break
eclipse a lot. The most current breakage (also reported as a Fedora bug)
is iirc still being discussed in upstream eclipse's bugzilla.
