Not that I can determine.  There's really no tools there that are build 
related.  Mostly things like less, groff, man, and ncurses.  I've been
trying to rebuild these and as I do, it doesn't seem to affect what I
see one way or the other.  Also, I notice that man and (I think) things
that use pipes (tar ztvf blah.tar.gz | more) hang, which may or may not
be the same problem!;-)
