after installing gstreamer 0.10.0, the pkg-config file installed still reports
verion 0.10:

Name: GStreamer
Description: Streaming media framework
Requires: glib-2.0, gobject-2.0, gmodule-2.0, gthread-2.0, libxml-2.0
Version: 0.9.7
Libs: -L${libdir} -lgstreamer-0.10
Cflags: -I${includedir}


this is quite annoying, as it's hard to make pkg-config find the package:

darkeye@tomodachi myplugin $ pkg-config --cflags gstreamer-0.10 >= 0.10
Package 0.10 was not found in the pkg-config search path.
Perhaps you should add the directory containing `0.10.pc'
to the PKG_CONFIG_PATH environment variable
No package '0.10' found
darkeye@tomodachi myplugin $ pkg-config --cflags gstreamer-0.10 >= 0.9
Package 0.9 was not found in the pkg-config search path.
Perhaps you should add the directory containing `0.9.pc'
to the PKG_CONFIG_PATH environment variable
No package '0.9' found
darkeye@tomodachi myplugin $ pkg-config --cflags gstreamer-0.9
Package gstreamer-0.9 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gstreamer-0.9.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gstreamer-0.9' found
darkeye@tomodachi myplugin $ pkg-config --cflags gstreamer-0.10
