This is not so good. The author should at least allow to distribute a
patched binary. Let me clarify it: We can distribute the intact and full
source code. But we must be able to change location of installed files (e.g.
path names), and we have to be able to make patches against bugs. We must
also be able to compile the patched sourcecode and distribute this (minimal)
modified binary. These are the relevant parts from
/usr/doc/debian-policiy/policy.html: (ver 2.2)
3. Derived Works
The license must allow modifications and derived works, and must
allow them to be distributed under the same terms as the license
of the original software.
4. Integrity of The Author's Source Code
The license may restrict source-code from being distributed in
modified form only if the license allows the distribution of
`patch files'' with the source code for the purpose of modifying
the program at build time. The license must explicitly permit
distribution of software built from modified source code. The license
may require derived works to carry a different name or version number
from the original software. (This is a compromise. The Debian group
encourages all authors to not restrict any files, source or binary,
from being modified.)

The last is not a problem. Because he did not requested a postcard *in the
copyright file*, we can live with the sentence "..., you should at least
send the author a postcard". It is not part of the copyright itself, is it?
Please contact the author and ask him to change the change the copyright a
bit to suite our policy. Mention, that XZX then can go in the main part of
