CRF++ in ports is at version 0.54, but the latest version, released 2013-02-13 is 0.58. It would be nice to have it updated.
@Elferdo, this port is currently unmaintained. It would be appreciated if you could provide a patch to update this port. If you need help, you can join #freebsd-ports on freenode IRC, or #bsdports Efnet, to ask for assistance.
requests for version updates aren't PR fodder per guideline. There's been no response to the suggestion to provide the upgrade, so closing PR for both reasons.
