I am attempting to build/install Ruby 3.2.2 open-source code on Windows using Visual Studio 2019. These are the steps I followed:

Using an x64 Native Tools Command Prompt (for Visual Studio 2019)..

1. cd C:\tmp\ruby-3.2.2
2. win32\configure.bat --prefix=C:\Ruby-3.2.2 --target=x64-mswin64 --disable-install-doc
3. nmake
4. nmake install

The error (on Step 4):

Downloading bundled gem files...
`RubyGems' were not loaded.
`error_highlight' was not loaded.
`did_you_mean' was not loaded.
`syntax_suggest' was not loaded.
c:/tmp/ruby-3.2.2/tool/downloader.rb:4:in `require': cannot load such file -- fileutils (LoadError)
        from c:/tmp/ruby-3.2.2/tool/downloader.rb:4:in `<top (required)>'
        from -e:in `require'
NMAKE : fatal error U1077: 'c:\tmp\RUBY-3~1.2\ruby.exe' : return code '0x1'
Stop.

Is this a bug, or operator error?

Doesn't nmake update-gems work too?
What does nmake -n update-gems show?
