Trying to install ddd

[Francisco Useche]

Hi:

I have been trying to install ddd.
I run both installation steps:
- ./configure
- make

without any problems. But when I try to run the program using ddd it
aborts saying:
" ./ddd: error while loading shared libraries: libXm.so.2: cannot load
shared object file: No such file or directory  "

I guess one library is missing but I have no idea how to make it work.

Do you know how can I make it to work?

Thanks
Francisco
