It looks like having pf and altq in your kernel don't work.  (I
thought our altq was decoupled)
I tried to build one and got the following errors:
Build directory is

Don't forget to run "make depend"
depending the kern library objects
depending the compat library objects
making sure the compat library is up to date...

They're all trying to use a struct altq_tag, which I couldn't find
anywhere.  (but I can't say I looked very hard)
