clicky unknown element class

I thought to play with clicky and compiled it

autoreconf -i
make install

previous had click

configure --enable-ipsec --enable-ip6 --disable-linuxmodule

Now, trying with my IPsec...

sudo clicky -r ../../conf/ipsec-echo-vtt.click

I get a display with all boxes on top of each other,
and

config:28: warning: unknown element class ‘IPsecAdapter’

What did I miss? Do I need to install some css file too?

And why doesn't it recognize my new class IPsecAdapter?

The application works just fine (replies to ping 10.0.0.3)
