Hello, for the archive: I believe I found the solution, validated on Win7 and MacOS.
This error occurs for any package that starts with "help". So "hell" is ok, "help12345" is not ok as a package name. Is this documented behavior? Apologies if I missed that. -----Ursprüngliche Nachricht----- Von: Duncan Murdoch [mailto:murdoch.dun...@gmail.com] Gesendet: Mittwoch, 9.

Nothing that you've written is reproducible by others. See if you can put together a short self-contained series of instructions that display the problems (or just one of them). It might involve installing from Github, or making a package tarball available somewhere.
