Just out of interest, what version of BladeLogic did this happen on?
Thanks - Lee
This is on 22.214.171.124. Our PS Engineer helped me "undelete" the lost system package (thanks again Stephan!), but it doesn't seem there is any way for me to figure out exactly what was in that dependencies dialog to see if it actually identified all the stuff it deleted. This is one of those that I assume will not really be resolvable (or even believed) unless others have the same issue.
