checking for OPENBOX... configure: error: Package requirements (obrender-3.0 >= 3.3.996 obparser-3.0 >= 3.3.996) were not met:

Package obparser-3.4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `obparser-3.4.pc'
to the PKG_CONFIG_PATH environment variable
Package 'obparser-3.4', required by 'ObRender', 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 OPENBOX_CFLAGS
and OPENBOX_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
