[plt-scheme] Error compiling DrScheme

  I just finished downloading DrScheme from CVS, and am getting the
following error when I try to compile it by running "make" after 
running "../src/configure --prefix=/usr/local/plt --enable-dynlib"

$ make
make mz

Configure didn't report any errors.  Can someone help me? Thanks.
