I filed a bug report about this problem a while ago:

   I traced this back as far as I could by looking at the Racket compiler
   source code. Compilation generates a temporary file in the same
   directory where the result is supposed to go. If no errors occur, the
   temporary file is then renamed to become the output. The partial stack
   traces point to locations in the code that do a recursive traversal of
   a library in order to compile everything. Unfortunately, the part that
   decides where the output goes is not referenced in the stack trace.

In my tests, all packages ended up working, but performance is indeed 
worse than with a Racket installation outside of Guix.

It would be nice if someone with more knowledge of Racket internals 
could give a hint or two for debugging this issue!
