The installed man page for pdftk already contains the formatted text, which yields to garbage when "man" tries to format it again. Attached is a changed ebuild which fixes this.
Besides, pdftk-1.41 is in Portage for more than one year now and doesn't have any open bugs regarding a stable environment, so please mark stable. It works fine for me on amd64.
The attachments also include a fix for bug 209802.

Patch to honor $LDFLAGS
This fixes bug 209802 together with the new ebuild.
Fixed in 1.41-r1, thanks! The stabilization will have to wait a bit, though.
