Hi, The README says:
* Notes: Glimpse is available from http://glimpse.cs.arizona.edu/. It is a fine piece of software, but the latest version (4.1) has been made non-free. I hope the University of Arizona reconsiders. However, we were using 4.1 so far... and 3.0 and 3.6 are also non-free just a bit more free. What's this note about then? :) I've switched to the binaries from the current 4.1-2 package since they use libc6 instead of libc5... -- Digital Electronic Being Intended for Assassination and Nullification
