 I've faced openssl 1.0.2e compilation issue.
 https://trac.macports.org/ticket/49916
 To get around the issue, I decided to install openssl 1.0.2d following
 https://trac.macports.org/wiki/howto/InstallingOlderPort

 I've got it installed
 ```
 $ port installed openssl
 The following ports are currently installed:
   openssl @1.0.2d_0 (active)
 ```

 But installing anything that depends on openssl, like curl I face an
 attempt to install the openssl port again.
 ```
 $ port install curl
 ...
 --->  Computing dependencies for openssl
 --->  Fetching archive for openssl
 ```
