"1.You must have the zip development libraries loaded on your system when building Bacula and Bacula must find this library, normally /usr/lib/libz.a. On Red Hat systems, this library is provided by the zlib-devel rpm."
I think this might be true even if you don’t compile it yourself.
On my Ubuntu servers when I compiled, I installed liblzo2-dev . Located: /usr/lib/x86_64-linux-gnu/libz.a
Or you might try LZO and see if that works.
