I am trying to make some changes to increase the buffer size in  
hpricot. I installed mingw and msys. When I run extconf.rb I get this  
error :  
checking for main() in c.lib… no  
creating Makefile

and then when I run the make file I get this:  
Makefile:127: \*\*\* target pattern contains no `%’. Stop.  
What am I doing wrong?
