Sage from precompiled package -- R plots

edit

Hello,

I installed Sage on my Debian Squeeze server using sage-4.8-linux-64bit-ubuntu_10.04.3_lts-x86_64-Linux.tar.lzma package. I wanted to use it mostly for R, and therefore tried some plotting, but I get the known X11 is not available message.

I installed packages recommended here in other questions, such as xorg-dev, libpango1.0-dev and libcairo2-dev, and restarted the worksheet, but with no results.

Do I need to recompile sage now?
