Anyway, h2xs is useful for building general modules, but it has a lot of stuff that is useful only for XS modules that you'll have to remove for PP modules. A better solution for PP is ExtUtils::ModuleMaker (reviewed here on PM).
FYI:
h2xs has an -X option to omit the XS portion. I normally create pure-perl modules with h2xs -XA -n <module-name>, as advised in the Perl Cookbook (recipe 12.8)
