Rotating latex

[Rune Zedeler]

I need some rotated latex stuff.
But when I use either rotating.sty or graphicx.sty latex fails from
within ly2dvi.
When creating clean latex-documents I have no problems using
rotating.sty and graphics.sty, so the bug is somehow caused by lilypond
or ly2dvi. I have no problems using other latex-packages.

I really need those rotated letters... Please help!

A second problem:
I need them to be vertically aligned.
Therefore I insert them on rhythmic staffs like this:

        \context RhythmicStaff = ra {
                s2_"\\key C" s2_"\\T.."

        }
        \context RhythmicStaff = rb { 
                s2_"\\key G" s2_"\\s.."
        }

        \paper{
            \translator {
                \RhythmicStaffContext
                \remove Staff_symbol_engraver;
                \remove Time_signature_engraver;

        }

The problem is that the two rhythmic staffs overlap.
I have tried 
        \property RhytmicStaff.StaffVerticalExtent = #'(-10.0 . 10.0)
and
        \property RhytmicStaff.RhythmicStaffVerticalExtent = #'(-10.0 . 10.0)
but nothing happens.

Generally, how do you set different engravers on different staffs?
removing the paper block affects, as you know, ALL staffs...
