 All destroot folders are always created on all architectures. It
 simplifies the implementation of the muniversal portgroup to do so.

 > Obviously I had to add muniversal 1.0, since it requires C++ 2011, and
 gcc11 (or any other supporting the standard) does not accept multiple arch
 flags.

 As I've mentioned elsewhere I don't think we should be adding the
 muniversal portgroup manually to every port that uses gcc on PowerPC
 systems just to accommodate universal builds on PowerPC. Either MacPorts
 base should do so automatically, or gcc should be fixed to accept multiple
 -arch flags. I would prefer the latter solution since using the muniversal
 portgroup can have other consequences with certain ports' build systems
 which include build failures.

 to fix it until Iain gets around to the real fix.

 I'm not familiar with the problem you're referring to or the workaround
 you're suggesting. Are you saying he should add
 `legacysupport.redirect_bins yes` to the graphviz portfile?
