I'm confused about the dpkg command.
Btw, I'm solemnly sorry but starting this thread as it has been done many time but I searched for answer but found nothing.
This is a freshly hd-installed Knoppix 3.3.

Ok like most I did "dpkg -i --force-overwrite libxcursor-dev_1.0.2-2_i386.deb" because "libxcursor-dev_1.0.2-2_i386.deb" is annoying.

root@box:~# dpkg -i --force-overwrite libxcursor-dev_1.0.2-2_i386.deb
dpkg: error processing libxcursor-dev_1.0.2-2_i386.deb (--install):
