[R] Problems with reshape2 on Mac

[Hadley Wickham]

Hi Uwe,

The problem is most likely because the original poster doesn't have
the latest version of plyr.  I correctly declare this dependency in
the DESCRIPTION
(http://cran.r-project.org/web/packages/reshape2/index.html), but
unfortunately R doesn't seem to use this information at run time,
generally creating many error reports of this nature.
