You should give "--enable-maintainer-mode" to "configure" to enable
maintainer-only portions of makefiles.

The reason for that is that some implementations of "make" (notably on
HP-UX) erroneously try to rebuild up-to-date targets.  So if some of the
targets may not always work (in this case - because Perl may be missing)
it's better to disable them by default.

AM_MAINTAINER_MODE is a controversial topic among Automake developers.
It's better to avoid it.  I'll change this rule if I have time.
