My guess on this is that you've not installed pthreads library in the 
/mingw path.  MinGW's GCC doesn't know how to find include files and 
libraries except in the include and lib directores relative to the bin 
directory where gcc.exe exists.  You'll need to modify the Makefile.in 
so that it adds -I and -L paths for your specified prefix if that is 
where you installed the pthread library.  Or you need to install the 
pthread library in the /mingw path.
