No. You just need the static versions of libz and png (libz.a, libpng.a).

It's found in the development packages, not the standard library ones.

libz hasn't changed much. Most programs shouldn't need a specific version.

Depends on the libc. For libc5, hello world grows by 100 KB if you
link it statically. uClibc is much better. The BusyBox fbset which
I made was only 40-50 KB total. Full-size glibc expands it by 500-
1000 KB.

You can always reinstall. It's not hard to download either a pristine
BL2 or BL3, on which the tiff programs work perfectly. Since tiffs are
so rare, downloading this is not very much of a bother. The user
probably already has it, anyway, if they're using BL2.

This runs tifftopnm with libraries from /usr/local/lib. You obviously
need to change it to choose options or run a different programs.

That will try to run every single program with libraries from /usr/local/lib,
which is just like copying everything from there to /usr/lib. Back to square
one, as I said.
