Error installing a self-made .deb package

Hi all. I created a package using checkinstall and set an 'architecture' flag to i686, since my machine is i686, i have an i686 kernel installed and use compiler flags for P4. Well, when trying to install a new package dpkg responds with the following:

package architecture (i686) does not match system (i386)

What i am doing wrong?

Type "dpkg --print-architecture" to double-check that you are specifying the correct architecture.
