    Trying to force pacman install?
    
    Pacman is completely broken. There must be some race condition or
    something because the exact same install command works or doesn't on
    consecutive builds, with several similar conflict errors:
    
    > mingw-w64-x86_64-gdk-pixbuf2: /mingw64/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.dll exists 
in filesystem
