This question really belongs on the macports-users mailing list, not  
the q-lang-users list, since your problem right now is with  
installing zlib, not q.

The message means that the zlib port is trying to install the file / 
opt/local/include/zconf.h but this file already exists on your  
system. Why does it? It shouldn't, unless you had a previous  
installation of MacPorts, removed it incompletely, and then  
reinstalled it. If that's the case, you should remove MacPorts  
completely [1] and reinstall it and then everything should work.

You can also force the activation of the zlib port. For each file  
it's trying to install which it finds to already exist, it will  
rename it, tell you about it, then install the file it was going to  
install. You can manually remove the renamed older files later. You  
should not generally need to go through all this, though. If you find  
this happening on many ports, something is amiss in your MacPorts  
installation, and the best idea is to remove and reinstall.
