libminizip built from the libkml source package is also used by the gdal
and osgearth source packages for KMZ (compressed KML) support.

libminizip built form the minizip source package is new in the archive,
currently only available in unstable.

Since the libminizip from libkml is used specifically for its KMZ
support, the bet course of action may be to rename the libkml library to
libkmlminizip and patch gdal and osgearth accordingly.

If the libraries are compatible (they both seem the be extracted from
zlib), it may be wisest to drop the libminizip from libkml.

Michael, what are your thoughts about this?

Kind Regards,
