Same here. Installation from source went fine. However at start it does complain for missing python bindings for QTWebkit. Same thing happens for Eric4, which can be installed via EPEL. It pulls the right dependencies, installs without complain but same error pops up when starting up. That means 2 of the major Scientific python IDE aren't working with EL6. Indeed, support for QtWebkit seem to be dropped by TUV, which is not a good sign: http://pkgs.org/centos-6-rhel-6/centos-rhel-i386/PyQt4-4.6.2-8.el6.i686.rpm.html Any suggestion for a workaround?
