Comment (by ShadSterling):

 Got aria2 installed

 `port snapshot --all --diff <snapshot-id>` includes
 {{{
  - aria2
    requested variants changed from '+cares+sqlite3-docs-gnutls-openssl-
 universal' to '+cares+docs+sqlite3-gnutls-universal'
    variants changed from '+cares+sqlite3' to '+cares+docs+sqlite3'
 }}}

 `port rdependents gss` does not include aria2
 {{{
 The following ports are dependent on gss:
   libgsasl
     curl
       cargo
       cmake
       git
       libgit2
         rust
       mupdf
       tesseract
 }}}

 Could adding +docs have removed a dependency?
