There is sb-check which will do a more thorough review of what you should
have installed.

I do not see your host listed but the Users Manual has a section for most
host operating systems with detailed instructions for installing the
dependencies. You need to use their package manager to install at least
bison and flex. You are likely also missing some development libraries

Check the users guide.
