Hi there,

I wonder if this is a bug. It seems all slime compiled lisp files are saved to ~/.slime except swank-loader. And when this is installed in a directory where the user has no write access, it will cause swank to fail.

This will happen if you are loading it through ASDF, and this is a usual behaviour of ASDF, so either use a writeable directory, or asdf-binary-locations, or don't use ASDF.
