How do i find missing dependents using the port command?

[Marius Schamschula]

Hmm.

I don’t have py-chardet listed as a py-acme dependency. I test certbot after each update, but in my case py-chardet was available, and thus no error occurred.

Will fix.

Apparently, that has died. And it turns out certbot doesn’t work anymore because some part of python is missing:
