Summary:                    missing lib -lz in libxml-2.0.pc
Description: 
Some configure steps of evience fail because libxml2 needs to link with
libz:

configure:20404: /opt/csw/bin/gcc-4.8 -o conftest -O2 -pipe -m32
-march=pentiumpro -I/opt/csw/include/nautilus

-L/opt/csw/lib conftest.c  -L/opt/csw/lib -lpoppler-glib -lgio-2.0 -lcairo
-lgobject-2.0 -lglib-2.0 -lintl -lxml2   >&5
Undefined                       first referenced

gzopen64                            /opt/csw/lib/libxml2.so
ld: fatal: symbol referencing errors. No output written to conftest

please add -lz to libxml-2.0.pc for linking libxml2.so

Hi Carsten,

I cannot reproduce the issue:

That means the library is self-contained and shouldn't need an explicit -lz
in pkgconfig,
