Could anyone help me with this error message that I am getting when I am try ing to configure liarliar, I have slackware 10.0 installed and I am using the kde desktop, gnome is installed but I am not using it.

checking for gtkmm-2.0 gthread-2.0 gstreamer-0.6... Package gtkmm-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtkmm-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtkmm-2.0' found

configure: error: Library requirements (gtkmm-2.0 gthread-2.0 gstreamer-0.6) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
