 Hi,

 after upgrading to El Capitan recently, I got this error in a previously
 working DDD setup, after upgrading a few X11 ports:

 ----

 Warning: No type converter registered for 'String' to 'Orientation'
 conversion.

 I searched through trac.macports.org and found out this error was last
 detected in 2009 on OS X Tiger. Previously I was running Snow Leopard and
 I didn't have any problems there.
  A little research showed that the culprit for this error most likely is
 xorg-libXaw, because that  after upgrading that port, DDD would not
 execute properly anymore.

 However, I am no expert in X11 so I could not find out exactly what
 dependency was missing. The DDD code itself is archaic, but the program is
 very useful - I use it as a GUI frontend to arm-none-eabi-gdb for embedded
 software development.

 I can confirm that DDD3.3.12 works on other X11 platforms without a
 problem (FreeBSD 10.2 and CentOS Linux).
