Linux and checkperms (continued)

["Ole Andre Rodlie" <olear%slackforge.net@localhost>]

Topic has been up earlier, but the issue is not resolved. My problem
is that checkperms (and others, but checkperms is the most important
since PKG_DEVELOPER demands it) breaks with the following error:

bmake: don't know how to make /usr/share/groff/tmac/mandoc.tmac. Stop

What is the problem? Is it pkgsrc/package? my system? (in that case,
what is broken/missing)

Would appreciate a solution, since I'm stuck on pkgsrc-2007Q2.
