You probably mean pkg-config --libs gstreamer-plugins-base-0.10, right?

This file will only give you valid CFLAGS and -L linker flags and
doesn't give you any libs. You have to check the content of the
libraries variable to see if the library you need is available and add
-lgst$(library)-0.10 to your linker flags yourself. This is intended
behaviour as you don't want to link to all plugins-base flags at the
same time most probably but only to a few...

In newer gstreamer versions this is fixed by adding a million new
pkg-config files:

$ pkg-config --libs gstreamer-audio-0.10
-pthread -lgstaudio-0.10 -lgstbase-0.10 -lgstinterfaces-0.10
-lgstreamer-0.10 -lgobject-2.0 -lgmodule-2.0 -ldl -lgthread-2.0 -lrt
-lxml2 -lglib-2.0
