# BEWARE
# The recent versions of homebrew/macOS can't add the libraries
# installed by Homebrew in the system's library search path, so
# Nimbus will fail to load RocksDB on start-up. THe new rules in
# macOS make it very difficult for the user to solve the problem
# in their profile, so we add an override here as the lessed evil:
export DYLD_LIBRARY_PATH="${DYLD_LIBRARY_PATH:-}:/opt/homebrew/lib"
