Hmm, did you install the curl port with non-default variants?

[ryandesign (Ryan Carsten Schmidt)]

Yes.

$ port installed curl
The following ports are currently installed:
  curl @7.60.0_0+darwinssl+http2+sftp_scp+universal (active)

py-curl: declare compatibility with various SSL backends of cURL

Closes: #56770

[ryandesign (Ryan Carsten Schmidt)]

Looks like this problem should be temporary. It was already ​reported upstream and allegedly ​fixed for the next version.

[ryandesign (Ryan Carsten Schmidt)]

Sadly still no new release of py-curl to fix this.

py-curl: allow building against curl with SSL backends unsupported by pycurl

Oops, I seem to have missed Ryan's comment. I've backported the upstream fix to the py-curl port. Please tell me if there's still something wrong.
