Upgrade to v370.  The port now unconditionally depends on Cairo
graphics.  Additional upstream changes include:
 - The conservative garbage collector (CGC) has been replaced with a
   precise garbage collector (3m) in the standard build.  For most
   users, this change simply amounts to "better performance in space
   and time".  Use the port knob 'CGC' to build DrScheme with
   the conservative garbage collector.
 - Unit-based servlets are no longer supported in the web server.
   Use module-based servlets, instead.
 - A new `(lib "unit.ss")' library replaces the old one and provides
   a simpler and more flexible syntax.
 - The HtDP "world.ss" and "image.ss" teachpacks have been revised,
   including support for the creation of animated GIFs and DrScheme's
   teachpack GUI now works only with the HtDP languages.  In other
   languages, use `require' to access teachpacks.
