ddd fails to compile

[David Judkovics]

After running 'configure that completes successfully 'ddd' fails to 
compile with the following error message,

If your program needs special terminal capabilities such as readline
or curses, let it run in the separate execution window
[ddd-3.3.8]# make                                              
Making all in readline
make[1]: Entering directory `ddd-3.3.8/readline'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `ddd-3.3.8/readline'
Making all in libiberty
make[1]: Entering directory `ddd-3.3.8/libiberty'
make[1]: *** No rule to make target `../include/xregex.h', needed by 
`regex.o'.  Stop.
make[1]: Leaving directory `ddd-3.3.8/libiberty'
make: *** [all-recursive] Error 1

Any help would be appreciated.

Thanks
