我正在跟进本指南安装 Hercules，一切顺利，直到第 3 步从源代码构建 - Linux 和 Mac OS X，我得到了以下结果：
hugolvc@HuLuVicaMacUbuntu:~/Downloads/mvs/hercules-3.13$ ./util/bldlvlck
This utility will check the level of various utilities needed to build
hercules. Checking is done against versions that are KNOWN to work.
This doesn't mean a build will NOT succeed with older versions
of the utilities, but will give a hint as to what package may need
an upgrade if the build ever fails with some odd reason.
OK autoconf requires 2.5, found 2.71
OK automake requires 1.9, found 1.16.5
OK gawk requires 3.0, found 5.1.0
OK gcc requires 3, found 11.4.0
OK grep requires 1, found 3.7
OK libiconv requires 1.8, found 2.35.0
OK m4 requires 1.4.6, found 1.4.18
OK make requires 3.79, found 4.3
OK perl requires 5.6, found 5.34.0
OK sed requires 3.02, found 4.8
问题出现在以下步骤中：
4. Generate the configure script:
./autogen.sh
它引发了这个错误：
hugolvc@HuLuVicaMacUbuntu:~/Downloads/mvs/hercules-3.13$ ./autogen.sh
bash: ./autogen.sh: No such file or directory
我还需要安装其他东西才能使用这个可执行文件吗？
