We have two libtool directories with two setup.hints in ~release/_obsolete and ~release. This is causing problems. It seems like things have been like this since at least November and no one was complaining because upset threw out the _obsolete package in favor of a newer one thanks purely to the fragile sort order directory inspection. That has changed now thanks to last week's problems.
People are complaining about getting out-of-date versions of libtool. Maybe I'll figure out the intent two seconds after sending this message but I can't see any reason to have two packages with identical names in the release so I have deleted the _obsolete/libtool packages. Looks like even error-checking for upset is in order. cgf
