| There's some .so files buried deep down:-
| 
|    chrisisbd@caracal:/usr/lib/x86_64-linux-gnu/zsh/5.7.1$ cd zsh
|    chrisisbd@caracal:/usr/lib/x86_64-linux-gnu/zsh/5.7.1/zsh$ ls
|    attr.so      complist.so   example.so   nearcolor.so  pcre.so     system.so
|    zleparameter.so
|    cap.so       computil.so   files.so     net           regex.so    
termcap.so
|    zprof.so
|    clone.so     curses.so     langinfo.so  newuser.so    rlimits.so  
terminfo.so
|    zpty.so
|    compctl.so   datetime.so   mapfile.so   param         sched.so    zftp.so
|    zselect.so
|    complete.so  deltochar.so  mathfunc.so  parameter.so  stat.so     zle.so
|    zutil.so
| 
| Will these allow me to build if I include that directory in the ld search 
path?
| If so, how do I include that directory?
| 
| If not then I guess I'll have to build ncurses as desribed in the E-Mail 
before.

Brendan's advice is the way to go.
