Re: where does package-get-info get its info from?

Well, some of the info does. Some of it comes from autoloaded forms in `_pkg.el' files in each package lisp directory. Because the package-index file it created was the same as the one you blew away. It'd just be a copy of the file that is in /usr/local/lib/xemacs-x.x.x/etc/. And... ...because you are a "Sumo-installer" and not a "PUI-installer", your package-index file never gets updated. Yes, I know that seems like a bug or flaw in the way XEmacs handles package management. But really it isn't. Sumo's are _not_ part of and have no knowledge of package management. Installing a Sumo would be like getting a RPM package, converting it to a .tar.gz and installing it with `tar zxf file.tar.gz'. The package would install and work fine, but the underlying RPM database would have no knowledge of it. So, the moral to this story is: If you want the XEmacs PUI tools to give you the best results, always install/remove/update your packages with PUI. Sure, use the Sumo's to set up a virgin installation, but once the Sumo is installed, continue maintaining the packages with PUI From that point on. I use the following incantation to keep all of my packages up to date... Tools -> Packages -> Set Download Site ...
