So I may have found an error in the BLFS 8.0 (stable) book.
Part 1. The link for the source for "ed" (a line editor) in the BLFS 8.0 stable book is a 404. I ended up going to
https://www.gnu.org/software/ed/ed.html to find it. Of interest: the book mentions a 1.14.1 version yet there appears to be none. The jump is from a 1.13 to 1.14.2 version.
Part 2. The ed source now has a .lz extension. tar in a BLFS 8.0 system will fail to untar this file. It looks like lzip needs to be installed. Lzip is not as part of a stock LFS system.
Part 3a. Compilation instructions and a link for lzip are not in the book.
Part 3b. It seems that lzip could be considered as a required dependency for ed?
In the mean time, time for me to make a lfs slackbuild for lzip
