The ddd help message suggests "changing the .blockTTYInput resource." whatever that is.
Do you have Motif 2.1 andlesstif both installed? If so, you shouldn't, they will conflict. Also, if it can't allocate the color grey, you may need more colors in X than what you have right now. What I would recommend you do is to get the lesstif and ddd packages from rawhide, they have been tested and ddd appears to work. You can get the lesstif and ddd packages at ftp://rawhide.redhat.com/rawhide/powertools/ , the packages are in i386, sparc and alpha, depending on your architecture. Please note that the ddd package is compiled against the lesstif in the above directories. Tim
