Comment (by homer3018):

 mmmh I see. Indeed I have some stuff in `/Users/seb/ports/devel/gnutls`,
 that are coming from the Darktable instructions, and this is where the
 v3.6.6 is coming from.

 I've tried (naively) to rename that folder and reinstall it, but it won't
 do it complaining that it can't access the folder. How can I told MacPorts
 that I don't want this folder anymore, I first want to install (the latest
 version) it normally and then path it again. I'm pretty sure that v3.6.6
 is the version that was the latest when I followed the Darktable build
 instructions for the very first time.

 Thanks for helping out ! much appreciated.
