ipcop 2.0.6 won't build - ulogd & libnetfilter_log

I've tried building the latest ipcop from svn on a clean slackware VM,
and it won't build.  ulogd stops as it doesn't have libnetfilter_log.
Here's the end of the log from the build:


checking pkg-config is at least version 0.9.0... yes
checking for LIBNFNETLINK... yes
checking for LIBMNL... yes
checking for LIBNETFILTER_LOG... no
configure: error: Package requirements (libnetfilter_log >= 1.0.0) were
not met:

No package 'libnetfilter_log' found

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_LOG_CFLAGS
and LIBNETFILTER_LOG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: *** [/usr/src/files_i486/03_ipcop/ulogd-2.0.2] Error 1


It looks to me that libnetfilter_log needs to be built before ulogd (it
isn't).

Please can you advise me what I need to edit so this happens.

Thanks
David
