Hi, sorry if this is a repeat, but an email sent to the [email protected] bounced back to me. We are attempting to install the DIALS package and CCTBX is required for compilation. During compilation of CCTBX, Xrender fails to find the X windows server. OS is Ubuntu LTS 12.04.5 text from console upon failure: Installing Xrender... log file is /home/dave/cctbx/build/base_tmp/Xrender_install_log getting package xrender-0.8.3.tar.gz... downloading from http://cci.lbl.gov/cctbx_dependencies : local copy is current using ./xrender-0.8.3.tar.gz (cached) installing xrender-0.8.3.tar.gz...
