I run:

 lintpkgsrc -r

and I get the following error:

Cannot open '/usr/pkgsrc/mk/../../mk/tools.mk' (from 
/usr/pkgsrc/mk/bsd.pkg.mk): No such file or directory

I just update pkgsrc so is something broken? It didnt do it before the update. 
I updated the full tree then just the mk subdir to make sure everything was 
synced up okay. But still I get the error. Any Ideas?
