[racket] Extending DrRacket with non-text tabs

Robby,

Thank you very much, I am happy now with editor running within DrRacket.

By the way, I have made a package, not with the full editor
itself (it is specific to my project), but with the base GUI class
(customizable).

I have registered the package on pkgs.racket-lang.org under the name
spreadsheet-editor. It fails to build, and here is what I am seeing:

http://pkg-build.racket-lang.org/server/built/fail/spreadsheet-editor.txt

require: PLaneT could not download the package "williams/table-panel:1": 
tcp-connect: connection failed
   detail: host not found
   address: planet.racket-lang.org
   port number: 80
   step: 1
   system error: Name or service not known; errno=-2
   in: (planet williams/table-panel:1:2/table-panel)

At the same time, it all works fine on my system. Do you have an idea
how can it be fixed?


Best regards,

Dmitry
