checking for GNOME... configure: error: Package requirements (libgnomeui-2.0) were not met:

No package 'libgnomeui-2.0' 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 GNOME_CFLAGS
and GNOME_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
