Don't you want ->toString(2)?

chmod 0664, $outfile;

that's not the right variable name. Aren't you using use strict; use warnings;?

autoflush XMLfile 1;

Useless, since closing a file handle flushes it.

binmode(XMLfile,":utf8");

That's a bug. "on document nodes [toString] returns the XML as a byte string in the original encoding of the document". You're double encoding. You want 

# Switch to UTF-8 if it's not already.
$config->setEncoding('UTF-8');

open(my $config_fh, ">", $configuri) or die $!;
binmode($config_fh);
print $config_fh $config->toString(2);
close($config_fh);
chmod 0664, $configuri;

or better yet: 
# Switch to UTF-8 if it's not already.
$config->setEncoding('UTF-8');

$config->toFile($configuri, 2);
chmod 0664, $configuri;
