# Before reinstalling all my libraries with profiling support I needed
# to use the --only install here (which prevents cabal from doing
# automatic dependency resolution) to avoid problems with conflicting
# reinstalls of Replib or unbound.
#
# Leaving these around in case those problems come back, in which case
# `make cabal-only-install` should be used.
