Thank you for the hint.  I am not very familiar with the vocabular of
TeX/LaTeX, and did not know that pdftex was something that xetex did not
have.  I guess from your commend that pdftex is a
product/implementation, and not a feature of TeX.

> You should use ifxetex and ifluatex, too.

Aha.  I'm testing by adding "\or\ifxetex" and it seem to work. :)

> Good hints are easily found also via google-that-for-me "ifpdf xetex"

Thanks, but it did not really help me.  I probably did not quite
understand the words used in the explanations.

No worries, I'll follow up with the createspace style developer that is
not in Debian (at least not yet). :)
