Hey,
I've updated the comps file in Fedora 20 to be more useful to application developers, and bug reporters alike.
This makes "yum install @gnome-software-development" install: - Command-line utilities like diffstat, valgrind, gdb - GNOME developer tools like gitg, gtkparasite - Additional libraries like clutter-gst-devel, polkit-devel - And devel docs for GStreamer, webkit, glib and clutter
Please take a look over the comps-f20.xml file in: https://git.fedorahosted.org/cgit/comps.git/
And let us know if, as GNOME/Fedora developers, there's anything else that ought to be installed by default for budding developers.
Not that this is for application development, not GNOME development itself, so things like totem-pl-parser, grilo, or gnome-online-accounts' devel packages are getting dragged in. Those should be pulled by "yum-builddep" instead, when you hack on a particular package.
Cheers
