Can't build asterisk on FreePBX anymore - mock Group buildsys-build does not exist

[qupfer (Henning Reich)]

For SRTP, I need a patched version of asterisk. I followed the last times this tutorial.
https://wiki.freepbx.org/display/PPS/Applying+patches+to+Asterisk+in+distro+SNG7
But now, this doesn’t work anymore and I have no Idea.
If I run the “make” command, after a short time, it fails with:

Group buildsys-build does not exist.
Error: Nothing to do

Maybe you are missing some development packages?

[qupfer (Henning Reich)]

Not directly, but I found a solution.
I have to change the mock configuration to use the package group “development” instead “buildsys-build”.
But I have no Idea why this is now neccessary. I also re-installed mock (incluse removing exisitng configurations), but it was allways configured to use the not existing group “buildsys-build”.
