Hi, It does work -- it seems like that at some point you've upgraded your R packages in an incorrect manner.
Specifically, it looks as if you've installed a new version of R and just copied over libraries from a previous (pre R-2.10.x) version.

In order to try automagically remedy the situation, you might try something like: R> update.packages(checkBuild=TRUE, ask=FALSE) After that's done, try re-installing gplots.
