Be aware that will likely cause problems if a program linking to your
library also links to libxapian directly or to another library which
uses libxapian internally - the issue is there will be two different
versions of libxapian loaded. If libxapian is dynamically linked
then this problem is avoided.

Sounds like you haven't linked to zlib. Dynamic libraries on modern
systems know which other libraries they depend on, but static libraries
are an ancient technology and don't - you need to specify the
dependencies by hand (or use xapian-config or pkg-config which paper
over this omission).
