#1 Cannot install on FC7

[Nikhil]

I'm having Eclipse 3.3.1 and i tried to install XulBooster on it!
It fired the following dependencies:
-WTP runtime
-WST runtime
-XSD
-Datatools
-GEF
-OCL

i have succesfully resolved the above and also have xulrunner and orangevolt's EclipseXUL alongwith it! where i have successfully installed XulBooster on WinZP platform, it isnt installing on a Fedora Core 7 with the same plugin packs tht i hv used for WinXP(i think they r platform independent)!
What may be the problem wit XulBooster? also, in WinXP, XulBooster's perspective wont load and same is the case with EclipseXUL. Im not able to run any XUL application, not even the sample app that appears wit every new project! :(
