Config error

Hi.

I tried to compile from source freesweep (a game). I got an error when
configuring but don't know what to do.

Here is the config.log generated :

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

It was created by configure, which was
generated by GNU Autoconf 2.52.  Invocation command line was

  $ ./configure
