excluding own-version-builds from being auto-updated

["Peter Lieven" <lieven@inity.de>]

Hello,

we customized a new apache-ssl deb package, by adding a module called
zmod to it. We need this module here in Germany for statistical
analysis.
Now every time a new apache-ssl version (or security fix) is available
our package is overwritten by apt-get dist-upgrade utility.

What is the common way naming the custom versions of packages (or
version number... etc), so that the package won't be auto-updated ???

Thanks
