# Special note for devs looking to upgrade this package:
#   ghc places a unique hash for each library when it is built.
#   Libraries depend on versions specified by those hashes.
#   This implies that all libraries need to be rebuilt when ghc is rebuilt.

# use the following command to print out packages that need to get rebuilt
# grep -r ghc /var/abs/ | awk -F '/' '{ print $5; }' | sort -u
