sej, after my last post, I continued looking at the ivtools thing, and cjwatson put me on the right track to know what happened exactly.
Basically, it looks like the RC bugs were open for a bit too much. ivtools got removed from testing, we think, at the beginning of April, on one of the rounds of removals. As the problems persisted for a while, woody entered the deep freeze (May 1st) and ivtools wasn't able to enter testing again.
I've read in the latest DWN that the Stable release manager is considering including packages that dropped from testing during the freeze in 3.0r1. I see there are still important issues with ivtools in its bugs (fails to build on some arches, apparently). If you want to try to get it in, the bugs need to be fixed. I'd be happy to try NMUing it, after asking Guenter, and then try to stick it in 3.0r1.
