Comment (by Dave-Allured):

 Would someone with a test version of macports-base (master), please try
 these commands:
 {{{
 port rdeps py38-attrs
 port rdeps --full py38-attrs
 }}}
 With 2.6.4, the first command currently prints 38 lines including a
 circular dependency only 2 levels down.  There is no special warning; you
 would have to notice the duplicate by eye.

 The second command goes to infinite loop with endless recursing console
 output, so don't run it on a hard copy terminal.   ;-)

 This is from unresolved issue #62277, but it is also a good test case for
 Joshua's current fix.
