The above are not errors. They are simply testing to see if the
autotools are available - so that if Makefile.am or configure.in etc are
modified the package knows whether to attempt to run (say)autoconf or to
return an error.

This is a problem. It could be permissions on the script, or it might be
a missing file if a broken tarball was downloaded, or it might be
something else needing further investigation.

Perl I think will be needed, but not automake and autoconf.

See my 2nd paragraphs comments :].

Definately check this.
