Marked as invalid in Ubuntu, as explained at debbugs #568393
grace's PDF support is deliberately disabled because PDFLib Lite isn't
DFSG-free software (no commercial use). It can't be linked both because it
would kick grace out of main into non-free, and because PDFLib isn't packaged
for Debian, so it's not an option even then. See README.Debian for the two
workarounds.
