if test -z "${LIBTOOLIZE+set}" && ( glibtoolize --version ) >/dev/null 2>&1

; then

        libtoolize=glibtoolize

    else

        libtoolize=${LIBTOOLIZE:-libtoolize}

    fi

because it selects glibtoolsize over libtoolize, even if autoconf etc. have been installed by the user (me in this case) ahead of the ones defined by the operating system (MacOS in my case).  Even worse, it then tells me:

But here’s what I get:

So: autogen.sh claims the libtool in the path is in /opt/local , which it is not, and

autogen.sh claims that the tools are in directories that they are not in (it always dropped “bin” - there is no requirement that the directory path end in bin.

I can work around these errors by setting LIBTOOLIZE, but I should not need to do that and I had to debug autogen.sh to discover what it really wanted.
