Hi Joachim!

Thanks for the bug report.

I think we should rather teach Lintian than 
/usr/share/cdbs/1/class/hlibrary.mk is provided by haskell-devscripts, 
rather than by cdbs itself. Or is your package including any other 
makefiles from /usr/share/cdbs/ ? (The package doesn't seem to be in the 
archive, so I can't check myself.)

We can't do that within the Lintian design constraints; see:
