ti manca pkg-config; apt-get install pkg-configcodice:checking for pkg-config... no checking for COMPIZ... 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 COMPIZ_CFLAGS and COMPIZ_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.
