open pixel file"... turned out that the

Weird problem after an upgradeStarted by:zabot, 10/26/2007 07:16PM
Hi,

I did an upgrade from kubuntu feisty to
gutsy and suddenly my
iraf stopped working (in fact I'm not
sure the upgrade is guilty since
there was some weeks I didn't use iraf).

Anyway. Before bothering you I tried to
uninstal and install iraf again....
