Hi,
I'm not sure what really happened, but you can fix this by editing 
"libtool" in 
"/0S/a11/0build/11.1-BUILD/mingw32-gcc-4.4.0/build/i386-pc-mingw32/libgomp".

Search for ".lib", and replace it with ".dll.a". Your first result 
should be line you need to edit. Sorry, I don't remember the line number.
