Comment 4 Bernd Feige 2020-08-26 08:21:29 UTC
I'm currently seeing this error (in the form of "ImportError: pycurl: libcurl link-time ssl backend (gnutls) is different from compile-time ssl backend (openssl)") whenever I import pycurl, with current dev-python/pycurl- and net-misc/curl-7.72.0.

Researching the case, the reason appears to be that I had set USE=gnutls globally, therefore curl was compiled with +gnutls but the default CURL_SSL only contains openssl. It seems that net-misc/curl-7.72.0 even defaults to gnutls when compiled with USE=gnutls even if CURL_SSL does not mention gnutls.

So probably the cleanup suggested in would also fix this bug.
