Just guessing -
The autoconfigure tool found an installed version of libgd, but it
was a 32-bit version rather than a 64-bit version.  So the test for
gd support in "./configure" succeeded, but the actual "make" command
failed.   If you do have a 64-bit libgd installed, you can probably
rescue things by hand-editing the Makefile so that instead of

  TERMLIBS =  ... -lreadline -lz -lgd ...

it says

  TERMLIBS =  ... -lreadline -lz -lgd64 ...
or
  TERMLIBS =  ... -lreadline -lz -L/some-64bit-lib-dir/ -lgd ...


It may also work to say instead
  ./configure --with-gd=/some-64bit-lib-directory/
but I don't know if that is sufficient on OSX.
