sync for #632 prepare

the minimun reqs for razorqt now changed:

i backported for lenny/squeeze:
* e2fsprogs
* libarchive
* cmake

and then build razorqt, minimum requeriments are cmake >= 2.8.7 that also requires e2fsprogs >= 1.41.8+(discard fix patches) and libarchive >= 2.8.3

so control file must be changed...
