That's weird, on my system without libnetfilter_cttimeout.

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBNETFILTER_CTTIMEOUT_CFLAGS
and LIBNETFILTER_CTTIMEOUT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

It didn't check our library path, should we add it in LIBRARY_PATH?
