help with an install problem

I hope someone here can help me with an install problem..

I just upgraded to Mac osx 10.1. When I try to configure --with-tcl I get an error
that 'wish' can not be found. Where do I get this? (this is not so important but I
would like to use pgaccess)

2.  below is the error I am getting from 'make' (included the output from make -v)
any ideas (I know that I can go back to osx version 10.0.4 but 10.1 is much faster
writing to the  screen.
