Happily I got this to work, largely by trial-and-error. In hopes that this will help somebody else, my config.site ended up being: OBJECT_MODE=64 R_PAPERSIZE=letter CC=/usr/local/bin/gcc MAIN_LDFLAGS=-Wl,-brtl SHLIB_LDFLAGS=-Wl,-G Which is virtually identical to that recommended in R-admin: one of my problems was using "-W1,brtl" rather than "-W1,-brtl". This was R 2.0.1

Hello, I have encountered some unexpected behaviour with levelplot that may simply be a misunderstanding on my part. If I create a levelplot from a matrix with named columns, some "padding" space appears at the top and bottom of the heatmap. Here is an example, and I've used panel.fill to make the space I'm speaking of evident (in green).
