checking for BERYL... gnome-config: not found
configure: error: Package requirements (libpng12 xcomposite >= 0.3 xfixes xdamage xrandr ice sm xinerama libstartup-notification-1.0 >= 0.7) were not met:

Package compositeproto was not found in the pkg-config search path.
Perhaps you should add the directory containing `compositeproto.pc'
to the PKG_CONFIG_PATH environment variable
Package 'compositeproto', required by 'Xcomposite', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables BERYL_CFLAGS
and BERYL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

provide an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
