I have successfully created a new package and the build runs through just 
fine, yay!

Unfortunately the installation into the user environment fails:

...
building path(s) `/nix/store/8jw7qly1mq2nzdjlnnhiqwgsbhwc3ns9-user-
environment'
created 8 symlinks in user environment
error: opening lock file `/nix/var/nix/profiles/default.lock': Permission 
denied

Does /nix/var/nix/profiles have to be writeable by the nixbld<n> users or 
the nixbld group? I searched the nix manual but found no hint.
