Bug fix release for Perl 5.8.4: some of the tests broke because they were naughtily exploiting a Perl bug re use strict inside (?{...}) constructions in regexps (see 01_mug.t/05_Parrot.t)
new shapes: map_world1, map_world2, map_world3, map_japan, map_uk

Build.PL: fixed for Module::Build v0.24 (_find_file_by_type changed)
