I have a private package file (attached). However, specifying this via -f to the new ghc-pkg has the following unpleasant consequences:
(1) -l only knows about the packages in my private file, not in the
GHC one.
(2) When I try to add a new package to this file that depends on one
of the GHC packages, it fails with the message
dependency `concurrent' doesn't exist
uni-package.conf
