Thank you - after removing --build=x86_64 from the configure command it seems to be compiling now.  For some reason, ffmpeg (my ultimate goal) is still not finding libvorbis when it tries to compile, but that seems to be another problem.  I am now getting a 'vorbis' folder in the includes folder, and various 'libvorbis*' files in the lib folder, so I guess libvorbis is no longer the problem.  Thanks again!
