编译cacti-spine-0.8.8a源代码，在make时出现如下错误：
../../libtool: line 454: CDPATH: command not found
../../libtool: line 1132: func_opt_split: command not found
libtool: Version mismatch error. This is libtool 2.2.6b, but the
libtool: definition of this LT_INIT comes from an older release.
libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6b
libtool: and run autoconf again.
只需要把源代码目录下的acinclude.m4文件删除，然后重新make即可。
