Where does this layout file come from?
It probably contains this line
# \DeclareLaTeXClass[beamer.cls,pgf.sty,xcolor.sty]{Beamer Presentation
Class}
which should be replaced by the following line:
# \DeclareLaTeXClass[beamer,pgf.sty,xcolor.sty]{Beamer Presentation Class}
(i.e. "beamer.cls" -> "beamer")
