Problem with installing JavaCV for Ubuntu

[lyuba]

I'm trying to set up a JavaCV with Eclipse following the guide:
http://code.google.com/p/javacv/wiki/UsingEclipseAndJavaCV

I've installed OpenCV from source with ccmake, it was automatically
placed to:
/usr/local/bin/, /usr/local/share/, /usr/local/lib/, /usr/local/
include/

I've manually included /usr/local/ to $PATH.

I tried to run the first example from here:
http://code.google.com/p/javacv/

And Eclipse cannot compile the code with the following error:

What am I doing wrong?

Thank you for your answer in advance!

It seems you forgot to add jna.jar from JNA 3.2.5...
