If this file (and others like it) are basically config files, you'll want to
make sure to properly handle them; see the config files entry on the
PortfileRecipes page:

<http://trac.macports.org/wiki/PortfileRecipes#configfiles>

If log files aren't registered as part of the port install (which they
usually aren't), then they shouldn't go away on uninstall.  If you need a
port-specific subdirectory of ${prefix}/var/log, then you need to create
that directory and use destroot.keepdirs so that it is kept around (see the
portfile(7) man page).

Upgrade basically just deactivates the port at the current version, then
activates the new version.  So you'll want to make sure the port is complete
at every version then not worry about anything else, save for the config and
log file bits mentioned above.
