MSYS2 package conflicts between pkg-config and pkgconf

When I followed github’s wiki to compile neovim on Windows, I got this warning from MSY2, dose this warning matter?

Here are my steps I performed
$ pacman -S mingw-w64-x86_64-{gcc,libtool,cmake,make,perl,python2,pkg-config,ninja,diffutils}
resolving dependencies…
looking for conflicting packages…
