[GRASSLIST:5080] d.zoom error on debian

[Martin Wegmann]

Hello, 

after I purged my system, d.zoom does not work anymore. I cannot zoom in or 
pan. Unfortunately I removed too many packages which I thought were obsolete. 
Does anyone know which package is necessary for GRASS to let d.zoom work 
again?

problem occurs with GRASS 5.3 as well as 5.7 cvs source
running debian testing

thanks in advance, Martin
