Dear Bug Team!
I've been running into a lot of those "Cannot open load file: "
messages. I've just realized that this is probably because the package
management UI does not check dependancies unless explicitly requested
to do so; it would probably be a good idea to have an option
(defaulting to on) to have it do this automatically at the beginning
of `pui-install-selected-packages' (aka "x"). If the check fails, the
user should probably have a choice between "include dependancies",
"ignore dependancies", and "cancel".
Also, having realized this, I tried to fix it with just
`pui-add-required-packages', but that refused to do anything unless I
selected at least one package first; perhaps this check should be
removed?
Of course, I'm a bit of an XEmacs newbie, so maybe I'm coming at this
all wrong, but even so I'm sure that improvements can be made (to help
newbies come at it from a better angle, if nothing else).

I recommend that you simply install everything in the XEmacs SUMO
package, and if you use non-Latin-1 characters much, the Mule SUMO
package as well.
I've just realized that this is probably because the package
management UI does not check dependancies unless explicitly
requested to do so; it would probably be a good idea to have an
option (defaulting to on) to have it do this automatically at the
beginning of `pui-install-selected-packages' (aka "x"). If the
check fails, the user should probably have a choice between
"include dependancies", "ignore dependancies", and
"cancel".
This doesn't do all that much good; the dependencies are build-time
dependencies, which means "anything we might want to inline when
compiling." Ie, typically the dependencies recorded are precisely the
dependencies you don't actually need! (In practice, it's not quite
that bad, but you will definitely get some packages you don't need and
not get some packages you do need.)
It's actually quite difficult to analyze the dependencies in Lisp,
because of features like autoloads, so that the declaration of the
dependency is in the *required* file, not in the *requiring* file.
Several attempts have been made, but nobody has ever followed through.
What really should be done is for Windows to install all packages by
default.
Also, having realized this, I tried to fix it with just
`pui-add-required-packages', but that refused to do anything unless I
selected at least one package first; perhaps this check should be

It's not a check. It's by design. PUI looks at the list of packages
you have requested, and gets *their* dependencies. It does not check
for unsatisfied dependencies of other packages, because it assumes you
have already got those dependencies you want, and any unsatisfied
dependencies are intentional. You can argue against that design if
you like, but it's unlikely that anybody will do anything about it
because in practice the straightforward thing to do is to install all
packages. Since the workaround is conceptually easy and disk space is
cheap, optimizing this is low priority right now.

Oh. Those are autogenerated compile-time dependencies? Maybe the UI
help should make that a bit clearer. I had naively assumed that they
were mostly human-written, run-time-needed dependencies. I guess
Debian has me spoiled.

Unfortunately, they're not even autogenerated for compile time.

Patches are welcome. The issue is now in the tracker, so somebody
should get to it eventually, but as I mentioned before, core people
aren't likely to get to it for a while.

Maybe we should do that everywhere. Over the past couple of decades,
downloading 36 megabytes became much less troublesome. Being able to
update packages without reinstalling is still useful, though.
