unable to run ddd on mac
I was able to fix this from some hints from this site. 

After installing, you run the configure command again. This will create the Ddd file in the ddd folder. Now you can follow any of the steps that are printed out, I personally used the DDD_HOME variable with the patch to the sourcecode directory of ddd, since Ddd is now in $DDD_HOME/ddd/Ddd.
