OK, so if I understand this part correctly, you were trying to first
update your already-installed gems by doing a "gem update" and, in the
process, it tried to update FXRuby?

Let's pretend you answered "yes" to that last question. What I don't
understand is why RubyGems is (apparently) trying to build FXRuby from
the source gem (fxruby-1.4.2.gem), instead of just installing the
binary gem for Windows (fxruby-1.4.2-mswin32). That strikes me as a
possible bug in RubyGems' "update" command.

OK.

OK, I see the problem. When the installer program
(FXRuby-1.4.2-ruby182.exe) asked you for the Ruby installation
directory, you must have input "K:\_Utilities\Ruby_1.8.2-15\FxRuby".
The correct answer would have been "K:\_Utilities\Ruby_1.8.2-15". This
is why Ruby couldn't find your installation of FXRuby (it was
installed outside of Ruby's standard search path).

Yes. I would first uninstall the FXRuby that you installed in the
wrong location (i.e. by using Windows' "Add/Remove Program" feature).
As for the borked gems, I would use the "gem uninstall" command to
remove all of the existing FXRuby gems that may be installed on your
system.

You should not need to do this if you provide the correct Ruby
installation directory to the installer.

Hope this helps,
