cvs-head compile question

Hi there, when I compile the head I get this message /usr/bin/ld: Undefined symbols: _ding _free_undo_list _rl_add_undo _rl_basic_quote_characters _rl_begin_undo_group _rl_bind_key_in_map _rl_binding_keymap _rl_char_is_quoted_p _rl_clear_message _rl_clear_signals _rl_complete_internal _rl_copy_keymap _rl_copy_text _rl_delete_text _rl_directory_completion_hook _rl_discard_keymap _rl_do_undo _rl_end_undo_group _rl_executing_keymap _rl_filename_dequoting_function _rl_filename_quote_characters _rl_filename_quoting_desired _rl_filename_quoting_function _rl_forced_update_display _rl_function_dumper _rl_function_of_keyseq _rl_generic_bind _rl_get_keymap _rl_get_keymap_by_name _rl_get_keymap_name _rl_ignore_some_completions_function _rl_insert_completions _rl_insert_text _rl_kill_text _rl_list_funmap_names _rl_make_bare_keymap _rl_make_keymap _rl_mark _rl_modifying _rl_named_function _rl_on_new_line _rl_pending_input _rl_possible_completions _rl_reset_line_state _rl_set_keymap _rl_set_signals _rl_unbind_command_in_map _rl_unbind_key _rl_unbind_key_in_map _rl_message collect2: ld returned 1 exit status <> make[2]: *** [stage2/ghc-6.5] Error 1 make[1]: *** [stage2] Error 2 make: *** [bootstrap2] Error 2 So what am I missing. Is it GTK+2? Do I really need it? Is there some way to compile the compiler without needing to bother with this? thanks, Jur
