Figured it out. zlib's website lists zlib.1.2.3 not the zlib.1.2.2 as

I now understand what FBBG means :-)

I don't think that's the problem. I just built an LFS 6.1 system, and used
zlib 1.2.3 (in fact the 6.1 errata recommends it) with no problems.
Chris, if the symlink points to libz.so.1.2.2 but the system only contains
libz.so.1.2.3 then at best anything linking against libz will link against
the static library. Normally, we can expect the package to handle this
sort of thing, but with libz we move the shared object ourselves.
Quite why we do this, and indeed why we even bother to install the static
library, is one of the things I've never got around to investigating ;)

I am not sure I understand what you're saying. If zlib 1.2.3 was installed,
then the 1.2.2 library and symlink should never exist anyway.
Hmmm, after looking at the book I see what you mean. The book's instructions
still mention symlinking to /lib/libz.so.1.2.2, so the errata should probably
mention that. Still, as I said, I did an lfs 6.1 installation using zlib
1.2.3 (and even forgot to change the symlink location to .so.1.2.3) but it
still worked fine. Weird...
I suspect you have linked against the static library (and that Krishna
probably didn't build the static library).

You probably want to use 2>/dev/null when you run it, or tee stdout to
a file, because stderr gets inundated with messages about uninitialized
values in pattern matches (don't remember that from previously, maybe
the latest perl is more demanding).
The definitive text for upgraded packages is usually to be found in the
development book. If you are indeed linked against the static library,
I'd better change the errata.
