Comment (by cal@…):

 I think this might be yet another occasion where Apple uses some hidden
 method that MacPorts doesn't know about and thus doesn't take care enough
 to avoid breaking. From what I've seen, this error seems to be thrown when
 curl tries to read the root certificates (but I'm really very much
 guessing here – the code is just too complicated and there's not enough
 publicly available documentation to know for sure).
 https://developer.apple.com/library/mac/documentation/security/conceptual/cryptoservices/CDSA/CDSA.html
 and http://pubs.opengroup.org/onlinepubs/9629299/9_chap01.htm might help
 to further debug this.

 As a shot in the dark, try opening Keychain Access.app and see if that
 fixes the problem. Are you changing to the root user before using MacPorts
 or do you use `sudo port …` – that might affect whether this works, too.
