py-emcee: Add py38-emcee subport

[lpagani91]

Please, can you make py38-emcee available ? Thank you.

it would also be good to update the port to its latest version. I know there are some (breaking) changes between versions 2 and 3). I would recommend updating the py-emcee port to version three (i.e., follow upstream) and if you need it to keep version two as py-emcee2 and make both ports conflict.

Thanks for the quick reaction but why can't I install it ?

coag>sudo port selfupdate

The ports tree has been updated. To upgrade your installed ports, you should run
  port upgrade outdated
coag_LP+HH>sudo port install py38-emcee

I tried to install the generic form :

sudo port install py-emcee

it worked (seemingly) but still not available inside python :

Remember to use WikiFormatting when writing in Trac.

It can take an hour for changes to propagate from the git repository to the rsync server. Try selfupdating again in a short while.

sorry for the formatting. I use it too rarely to remember. :-(

OK for the propagation but what is the py-emcee then ?
