You seem to have installed a recent version of HTML::EP. There have been
important changes in the current version that may break existing code:
The "epparse-" and "epperl-" attributes have been removed. See the CHANGES
section in the manual for details. (In short all you have to do is removing
the "epperl-" and "epparse-" markers, the package ought to detect
automatically that it should parse or evaluate attributes.)

MSG
    } elsif ($version < 0.2000) {
	print <<'MSG';

You seem to have installed a recent version of HTML::EP. Version 0.2
has changed a lot of internals. So far there are no known incompatibilities,
but if you have existing applications built on top of EP, you should
either not install this version or carefully check your application.
If you encounter any problems, let me know:
