That's the thing. I thought the debian packages had to be compiled for the target architecture from the source tarball.
Looking for the stable debian package for aspell, I found the .tar.gz, .dsc, and diff.gz. files you mentioned here: http://packages.debian.org/source/stable/aspell . Will running "dpkg-buildpackage -rfakeroot" build a .deb file that will install on the N900.
Can you point me to some documentation that explains all the steps to build the package? Thanks,
