devel/gettext, as of version 0.19.3, has been split into three ports:
devel/gettext, the meta-port depending the two next ports;
devel/gettext-runtime, the runtime libraries; and
devel/gettext-tools, the tools for managing the message catalogs.
In my case, as I build my own ports, making the transition required manual intervention using both
portupgrade and the ports collection tree:
portupgrade -fpvo devel/gettext-runtime gettext cd /usr/ports/devel/gettext-tools && make && make install && make package && make clean cd /usr/ports/devel/gettext && make && make install && make package && make clean portupgrade -fprvx gettext -x gettext-runtime -x gettext-tools devel/gettext-runtime
