Apparently you're building an Intel application (-arch i386)...

...but the hunspell library you've got (did you build that from  
source, too?) doesn't include Intel code.

OK, now I start speculating: I think you're running on a PowerPC Mac.  
However, the TeXworks project file (.pro) is set up to build universal  
binaries by default, so Xcode will compile for both architectures.

But when you built hunspell, the configure process detected a PPC  
machine and built a PPC library. So the TeXworks build fails when  
trying to link the i386 version of the code.

Solution? Two possibilities:

(1) Edit TeXworks.pro and remove the line

         CONFIG += x86 ppc

and then re-run qmake to create a fresh Xcode project. Without that  
CONFIG line, it will build a single-architecture app for your  
platform, which is fine if you're not planning to share it with other  
people on other kinds of machine.

(2) Re-do your hunspell build, setting an appropriate environment for  
the configure script so that it builds a Universal library. What  
options would that require? Sorry, I don't remember offhand! Something  
along the lines of

     CC='gcc -arch ppc -arch i386' CXX='g++ -arch ppc -arch i386' ./ 
configure

might do it, but there may be additional variables you have to adjust  
as well.
