As usual, it is recommended to rebuild or reinstall all the dependent ports and the lang/ghc port itself in one of the following ways: # portmaster -w -r ghc or # portupgrade -fr lang/ghc In case of pkg(8), it is probably safer to remove all the GHC-dependent packages along with GHC and reinstall everything from scratch. For example: # pkg query "%ro" ghc > ghc-pkgs.txt # pkg delete -y lang/ghc In ghc-pkgs.txt, check and remove all the packages that have been moved on the update, then use this command: # pkg install -y `cat ghc-pkgs.txt` Approved by: tcberner (mentor) Differential Revision: https://reviews.freebsd.org/D16038
