[XeTeX] Errors compiling Latex-Beamer with XeTeX

[Alan Jones]

Hi:

After getting moderncv to work, I want Latex-Beamer to work with
XeTeX. I get errors compiling Latex-Beamer presentation with XeTeX.

I get this error first.

(/usr/share/texmf/tex/generic/pgf/systemlayer/pgf.cfg)

! Package pgfsys Error: Driver file ``pgfsys-xetex.def'' not found..

See the pgfsys package documentation for explanation.
Type  H <return>  for immediate help.
 ...

l.891 ...ver file ``\pgfsysdriver'' not found.}{}}

? x
No pages of output.

upon downlaoding pgfsys-xetex-def, I get this error

(/usr/share/texmf-texlive/tex/latex/graphics/dvipsnam.def)
! Undefined control sequence.
\set at color ->\pdfliteral
                         {\current at color }\aftergroup \reset at color
l.1448 \color{black}

?

Has anyone Latex beamer working with XeTeX.

Thanks,
AJ
