webrev -f failing on Mac

[Pete Brunet]

Hi, I'd like to create a multi-repo forest webrev using webrev -f.  I
just tried that for the first time on Mac and it doesn't work.

I followed instructions here:
https://www.mercurial-scm.org/wiki/ForestExtension

and used forest.py from the suggested link and that site indicates rev
0.9.1, or at least that's the latest tag.  The last commit was 10/9/11.

I suspect it's incompatible with my version of Mercurial, 3.0.1
https://bitbucket.org/gxti/hgforest/issues/3/hgforest-incompatible-w-mercurial-23

Is the forest extension still in use?  If not is there another solution
to a forest wide webrev?

Pete
