There was a related problem that Sam noticed a while back about how the same set of parameters (if not the same uses) leaked out into his program and the best I came up with was the advice to disable the automatic compilation in DrRacket (in the language dialog's "show details" section).<div> </div><div>Robby On Friday, February 1, 2013, Matthew Flatt wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I think the issue is that DrRacket sets `use-compiled-file-paths' to include "compiled/drracket/errortrace", and the installation doesn't includes compiled files there, so CM tries to add them. In other words, there's a collision between your use of CM via `managed-compiled-zo' and a use already in place for the load handler. You can work around the problem by setting `use-compiled-path-paths' back to just `(list "compiled")'. Meanwhile, I'm not sure which part of the system to blame. I think the pile of parameters and callbacks isn't right, since DrRacket interferes with your program, but I don't immediately see how to fix it.
