Hi, sorry if this is a repeat, but an email sent to the cctbx@cci.lbl.gov 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...

    raise RuntimeError("Call to '%s' failed with exit code %d" % (args, rc))
RuntimeError: Call to './configure --prefix="/home/dave/cctbx/build/base"' failed with exit code 1

​Log file indicates everything fine till X is required then :​
checking for X... no
configure: error: X is required, but it was either disabled or not found.

​any suggestions as to how to proceed would be appreciated
thanks,
