PGI 15.10 on El Capitan, license manager not working

I installed PGI Workstation 2015 (15.10) on OSX El Capitan, with XCode 7.1, but I’m unable to have the license manager up and running. Step 6, pag.39 of installation guide is not working, since com.pgroup.flexlm.plist is not in /opt/pgi.

The software is running with the trial key.

Any clue?

Xcode 7.1 will not be supported until the 16.1 release in January (or later).
