Ok here's my contribution - I hope it is helpful:

I don't know what to do except follow Wilson's instructions if you
don't already have a working compiler.  But if you already have a
commercial VisualStudio .NET, there should already be a vsvars32.bat
under ...\Common7\Tools.  There will probably also be a shortcut to it
called "Visual Studio Command Prompt" in the program menu under
VisualStudio .Net Tools.  So to compile ruby for yourself:

1) Download and unzip the ruby source
2) run vsvars.bat
3) then in that command prompt run the attached batch file
>buildruby.bat SOURCE_DIR [ INSTALL_DIR [ BUILD_DIR ] ]

where SOURCE_DIR is the path to the source
(<unzip_location>\Ruby-1.8.4 if you got the latest stable version) and
INSTALL_DIR is the location you want ruby to go.  They must be
different directories.  The intermediate files go into BUILD_DIR,
which defaults to INSTALL_DIR/Build if you don't specify it.  All
these paths can be absolute or relative.  SOURCE_DIR must exist and
contain ruby source,  but the other two will be created if they don't
exist.

4) change to INSTALL_DIR and type ruby -v.

Tada!

This is tested with Visual Studio .NET and Visual Studio .NET 2003, on
Windows XP and
Windows 2000.  Please let me know if you find any issues with it.  I'd
especially like to know if it works after following Wilson's
instructions to the point of creating vsvars.bat.
