Hmmm. You appear to have the Astro::FITS::Header module installed, which
is good, but it's version $Astro::FITS::Header::VERSION -- 
which doesn't help PDL (need >= 1.12, i.e. distribution >= v2.1).
Using internal fallback code.

Hmmm. You don't appear to have the Astro::FITS::Header module installed.
You'll be able to read and write simple FITS files anyway, but FITS support is
greatly improved if you install it.
