...was (finally) able to install it (after installing blas and gcc-fortran). I can start an R session and do computations. When I try to do any graphics using x11, I get the message: unable to load shared library '/usr/lib/R/modules//R_X11.so': /usr/lib/R/modules//R_X11.so: undefined symbol: cairo_image_surface_get_data Does anyone have an idea on how to fix this?

R-devel has new versions of the X11(), png() and jpeg() devices on Unix-alikes. The intention is that these are used identically to the previous versions (which remain available) but will produce higher-quality output with more features. Pros: Antialiasing of text and lines (can be turned off) but no blurring of fills. Buffering of the X11 display and fast repainting from a backing image.
