This is the problem for using old latex2html (ex. version 2017) 
and new perl (ex. version 5.26). In new perl, current directory
'.' is not in @INC.

You insert it (or 

  push(@INC, ".");

) to your .latex2html-init file in your home directory, or 
current directory.

Another solution is to modify your latex2html script from

    require ("${PREFIX}internals.pl") if (-f "${PREFIX}internals.pl");

to

    if (-f "${PREFIX}internals.pl") {
        my $file = "${PREFIX}internals.pl";
        if ($file !~ /^\Q$dd\E/) {
            $file = ".$dd$file";
        }
        require ($file);
    }
