$ cat config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU Libtool configure 2.4.2, which was
generated by GNU Autoconf 2.68.  Invocation command line was

  $ ./configure --disable-dependency-tracking --prefix=/usr/local/Cellar/libtool/2.4.2 --program-prefix=g --enable-ltdl-install
