You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 gperf @3.1
 icu @58.2
 db48 @4.8.30+java
 ncurses @6.1
 gettext @0.19.8.1
 llvm-3.4 @3.4.2
 pcre @8.43
Continue? [Y/n]: Y

so ... I've set it to do this ... this will take some hours barring any
errors ;-) :-)
