[swfmill] Impossible to compile from sources

[Will]

Hi - so I just checked out trunk from svn on OSX 10.4 so I can get the 
latest patches, I ran ./autogen.sh but hit the ./configure: line 18836: 
syntax error near unexpected token `XML,'

I've read through the old mailing list thread of compiling on OSX from 
May 2007 and that seemed to end inconclusively as did the recent Nov 
thread of "Impossible to compile from sources". Is there a known 
technique for doing so? Is the May thread the way to go?

thanks
Will
