You need to tell "port clean" what you want it to clean. For example,  
"sudo port clean bison" would clean the bison port's work directory.

So the problem here is with expat, not bison. And it says it cannot  
find a compiler. Did you install Xcode? You need to. The current  
version of Xcode is 3.0 for Leopard, 2.5 for Tiger or 1.5 for  
Panther. Please download and install the correct version from http://
