checking for CSM... configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables CSM_CFLAGS
and CSM_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://www.freedesktop.org/software/pkgconfig>.
See `config.log' for more details.
