If you're having trouble compiling it, then you should post errors you
got. If everything went OK the second time (including the test suite),
then there's probably nothing to worry about.

 I have built LFS a few times, 6.1, 6.3, 6.4 and 6.7 to be exactly.
Haven't built 7.0 because I don't have time to manage all stuff by
myself now. Packages are updating way too fast, so I went back to
Ubuntu. Though, I might start LFS soon again, I probably have to build
a linux system for a embedded ARM system, and I think LFS will work
too (with cross compiler ofcourse).
If you need any help, feel free to ask!
