second macports installation (culprit found)

[Daniel Oberhoff]

Hi,

After running into the same problem as before (reversed, this time the  
second installation accessed the tcl package of the first) I finally  
found the culprit:

On the macports docpage on the web it says to specify the tcl package  
installation directory via --with-tcl-package, which I used, but  
actually it is --with-tclpackage (note the missing "-"). Now configure  
just merily ignores that, so it never occured to me that it was wrong.  
I would suggest to a) have configure bail out on the unknown option  
and b) correct the docs to spare other users from running into the  
same problem.

Cheers

Daniel
