I didn't even realize that this is the mzscheme package.

* The problem seems to be that the debian package does its own
  division of the directories into what goes into the mzscheme package
  and what goes into the drscheme package.  We have a script that does
  that job and verifies that no dependencies are broken.  Another
  solution is to have a single plt-scheme distribution.

  In any case, there need to be some overall reworking of the
  directory choices, since in version 4 the collections tree changed
  significantly.

More problems that you may want to file bug reports about (or maybe
Ari will see this email anyway):

* The "big" package should be named `plt-scheme'

* Unless its distributed in source form, there shouldn't be a
  dependency on gcc.

* IMPORTANT: the build should not use cgc -- it should use the default
  3m.  The cgc version of mzscheme can suffer from potential memory
  leaks, and this is especially important with long-running processes
  like a web-server (and my guess is that the mzscheme package is
  particularly popular for running servers).
