  No, xmlsoft.org is a RHEL-5 system, and libxml2 from git configures
and compiles just fine there.

xmlsoft:~/libxml2 -> nm /usr/lib/libz.a | grep gzopen64
xmlsoft:~/libxml2 -> grep gzopen64 /usr/include/zlib.h
xmlsoft:~/libxml2 -> rpm -Vp /usr/lib/libz.a /usr/include/zlib.h
xmlsoft:~/libxml2 ->

 I would guess you have some random zlib.h laying around exposing
gzopen64 and that the system library don't support.

 In general not maintaining your system with rpm generate this kind
of random problems, and nobody will be able to be sure of what's
going on.
