I was only doing it because of namespace locked errors, which now seem
to be gone.  I was trying to do everything in the global namespace.

Do you mean that R must be launched from inside the package directory?
Or at least have the current working directory inside the package?  I
haven't been doing that.  ESS has seemed aware when a particular file
was in a package regardless of where R is running (I was using C-c C-t
C-s to put things in the global namespace; using the package namespace
was automatic).

I haven't been using devtools, partly (as I recall) because they force
certain other tool choices.  But I might have another look.
