DDD 3.3.12 (i386-apple-darwin16.1.0) gets Xt error

[Mick]

I do the following things on macOS Sierra(12.2.1):

brew tap homebrew/x11

brew install openmotif lesstif

brew link --overwrite openmotif

brew install ddd

brew link --overwrite lesstif

When I run 'ddd' on iTerm2, it produce this error:

Error: Unresolved inheritance operation

Xt error (Unresolved inheritance operation).
