Error compiling ns-3 waf (Could not load the Waf tool 'clang_compilation_database)

I update my ns-3 version (including private modules) to the last release and when compiling, this is the error generated:

Someone has an idea about what I'm missing?

[EDIT: add of the config.log file]

Super old, but still found this problem relevant today. In my wscript, with ns3 in particular, the tooldir is waf-tools, so you want to do something like:

def options(opt):
    opt.load('clang_compilation_database', tooldir='waf-tools')

def configure(conf):
    conf.load('clang_compilation_database', tooldir='waf-tools')

Found this useful for trying to setup clion with ns3: How to setup CLion to use waf as build system

Try to remove the build folder either manually (rm -f build) or with ./waf distclean and re-configure.
