-------------------------------+----------------------------
 Dear all,

 I am facing an issue I cannot seem to be able to solve myself. I am trying
 to install jupyter notebook and the latest version of the port gives me
 the 6.4 while it conflicts with the latest version of traitlets for some
 warning issue (from what I have understood from my browsing various forums
 on the web).

 Here is the message I get

 }}}

 Most answers I found point to the fact that notebook is calling for a
 private method of traitlets called warn while it should be calling for
 warnings.warn, which is public. I'd like to push forward a newer version
 of notebook (7.x.x?) but that involves a lot of dependencies and I don't
 know which ones must be pushed forward. In the meantime, I'll work out a
 dirty hack, if I can...

 Thanks for the help and for the fix, if possible. If there is something
 wrong on my side, I am happy to be taught (I just uninstalled/reinstalled
 macports to fix this). It was working with python38 and broke since I am
 trying to move to python311 (yeah, I know, I am late...)

 Cheers,
 R
