Thank you for this ebuild, you may also want to investigate putting your ebuild in the sunrise overlay which is located at http://www.gentoo.org/proj/en/sunrise/. When/if the ebuild is put into sunrise, please let us know on this bug.
I haven't had a chance to post to sunrise yet. There is a better ebuild for 0.5 here: http://overlays.gentoo.org/dev/suka/browser/app-text/pdfmod (its linked from http://live.gnome.org/PdfMod)
