checking pkg-config is at least version 0.9.0... yes
checking for BERYL_SETTINGS... configure: error: Package requirements (            gtk+-2.0 >= 2.8.0             beryl) were not met:

Package xcomposite was not found in the pkg-config search path.
Perhaps you should add the directory containing `xcomposite.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xcomposite', required by 'beryl', 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_SETTINGS_CFLAGS
and BERYL_SETTINGS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
