There is a faq topic I found on that.

What if the user interface can't connect to server?
This problem can be caused if OpenDX wasn't installed using the
standard install process. If you have to type a
pathname in front of the "dx" command to start the User Interface, the
User Interface will not be able to start the server
part of DX. To fix this, add the "<PREFIX>/bin" directory to your
search path.
But that may not be your problem since you start with "dx" and seem to have a
standard installation. Maybe with
ldd dxexec
you could check if any of the dynamic libraries are not found. Then you could
expand your LD_LIBRARY_PATH to resolve the problem.
But this is only a guess, the pros may be of more help,
