I am trying to use the set of commands to get cctbx from SVN (http://cctbx.sourceforge.net/current/installation.html#using-the-cctbx-svn-r...). However, either I am unable to follow the commands or something is not configured properly. I did the following steps: svn export https://cctbx.svn.sourceforge.net/svnroot/cctbx/trunk/libtbx/development/cct... /bin/csh cctbx_svn_getting_started.csh mkdir cctbx_build mv sources cctbx_sources cd cctbx_build python ../cctbx_sources/cctbx_project/libtbx/configure.py iotbx source setpaths.sh make Make fails almost immediately. I have listed the output from configure and the error from the make command on a gist (https://gist.github.com/3912960). I just checked: if I configure using mmtbx instead of iotbx then building the package works. --Jeff
