package dependencies

Hi, everybody, First of all many thanks for all the good work. Then the grisly details... :) :) I'm trying to use the new package interface, but i ran into a lot of problems mostly due to "unexpected" package dependencies. If I install the sumo tarball everything is ok, but otherwise... Currently I have a problem with add-change-log-entry. I discovered it needs mail-lib, but that doesn't seem to be enough, since it complains with: "Wrong type argument: sequencep, mcondarelli(a)soft-in\.com" and I don't know what else is missing ;^( (by the way: is there a way to paste that kind of messages? if I try to select it it disappears). Another different (but quite annoying) i noticed with the latest (???) "20 minutes to Nikko" (linux, Mule) version (on a P266) is that "sometimes" (I wasn't able to define exactly when, but the machine is not loaded at all) deleting (I'm using delete-key-delete-forward, if that matters) becomes very slow, so autorepeated keys accumulate and the deleting continues (several seconds and up to a couple of full lines) after i release the delete (or backspace) key. Any idea of why that's happening and how to pinpoint the problem? TIA Mauro
