Yeah, this is a totally non-obvious part of the way Julia's package manager
works, "rm" doesn't delete anything, it removes the requirement for the
package to be installed then re-runs dependency resolution. Packages that
are no longer required don't get deleted, they get moved to .trash.
Sometimes this is a good thing, but often it results in trying to put back
a broken copy of the package instead of re-starting from scratch.
I have a proposal I opened a few weeks ago to tweak some of this behavior,
still need to put together a prototype implementation of my suggested
change.
