Re: Installation issue in Mac OS Big Sur

Hi Mathieu,

thanks for the report. You can report issues at the users list see

https://pairlist2.pair.net/mailman/listinfo/reportlab-users

So macintosh is now deprecated. I guess there's an OSX flag or somesuch.

 From the fact that you are building the package yourself I assume that this
pypi package doesn't work for you on you improved OS

which I build with multibuild on travis.


Unfortunately multibuild hasn't advanced beyond 10.9, but perhaps that's an issue with travis as well.
