+[pdftk][] is a useful tool for manipulating PDFs.

+Unfortunately, there's a [bug][] in [[Gentoo's|Gentoo]]
+`app-text/pdftk` package.  The build eventually crashes with:

+    g++ -DPATH_DELIM=0x2f -DASK_ABOUT_WARNINGS=false -DUNBLOCK_SIGNALS -fdollars-in-identifiers -DPDFTK_VER=\"1.44\" -Wall -Wextra -Weffc++ -O2 -I../java pdftk.cc -c
+    pdftk.cc:60:39: fatal error: com/lowagie/text/Document.h: No such file or directory

+Which is due to a bad `-m64` option brought in by `CFLAGS_amd64`:
