know what's wrong?

I installed FANN without any special settings in ./configure,
installed ruby-fann, tried to enter IRB to try your test code... I get
what I think is ruby error @ end... Any help you can provide in
troubleshooting?

Looks like it's an IRB-specific error, as I got sample code to run if
i just pasted everything into a .rb file

Yes, I got the same results. I will look into the IRB problem and
post findings here.
