TAB not jumping to OK in options screen

[n dhert]

I installed a new FreeBSD-8.2 system
and installed a few ports, no problem
Then I do want to install Xorg
# cd /usr/ports/x11/xorg
# make install clean
At the package libxslt 1.1.26_3 it gives me an options screen.
I hit TAB to go to the OK button, but it just moves the cursor 8 postions
to the right on the same line.
I can't get to the OK prommpt
With the several packages I installed before I had no problem with the
usage of TAB in the options screen.

What can be the cause and how to fix it?
