Done.

It's not that bad. There are quite a number of changes by now anyway
which have to be applied every time the xpdf package in swftools is
upgraded.

Are you saying that you need to use the "right" languagepack for
every PDF, but can't have more than one around?
Or would you also be able to just include *all* languagepacks, and then be
able to convert every PDF, no matter the language?

Ok- I renamed the xpdfrc config files now anyway.
Config files now processed are:

/etc/pdf2swf.conf
$HOME/.pdf2swf.conf

So if you're o.k. with putting the languagepack parameters into, say,
~/.pdf2swf.conf, we wouldn't need any other changes to pdf2swf.
(Probably the only way to beat that approach in terms of convenience
 would be to introduce a --languagepack option to pdf2swf which you can
 point directly to the .tar.gz file you downloaded from the xpdf
 download page ;))
