how can I make sure? I have libz.so.1 from OpenCSW installed:

ls -l /opt/csw/lib/libz.so.1
lrwxrwxrwx   1 root     root          13 Apr  7 18:57 
/opt/csw/lib/libz.so.1 -> libz.so.1.2.7

The linker ought to prefer this one? ldd says something even different:
ldd libxml2.so.2
         libdl.so.1 =>    /lib/libdl.so.1
         libpthread.so.1 =>       /lib/libpthread.so.1
         libz.so.1 =>     /opt/csw/lib/sparcv8plus+vis/libz.so.1
         libiconv.so.2 => /opt/csw/lib/sparcv8/libiconv.so.2
         libm.so.1 =>     /lib/libm.so.1
         libsocket.so.1 =>        /lib/libsocket.so.1
         libnsl.so.1 =>   /lib/libnsl.so.1
         libc.so.1 =>     /lib/libc.so.1
         libmp.so.2 =>    /lib/libmp.so.2
         libmd.so.1 =>    /lib/libmd.so.1
         libscf.so.1 =>   /lib/libscf.so.1
         libdoor.so.1 =>  /lib/libdoor.so.1
         libuutil.so.1 =>         /lib/libuutil.so.1
         libgen.so.1 =>   /lib/libgen.so.1
         libm.so.2 =>     /lib/libm.so.2
         /platform/SUNW,UltraAX-i2/lib/libc_psr.so.1
         /platform/SUNW,UltraAX-i2/lib/libmd_psr.so.1


my linking line is:
gcc      -shared-libgcc  -pthread -fexceptions -fgnu-runtime -o 
GSspell.service/./GSspell \
./obj/GSspell.obj/GSspell.m.o   -L/opt/csw/lib -R/opt/csw/lib

gzopen64                            /opt/csw/lib/libxml2.so.2

which would include /opt/csw/lib but not the particular 
/opt/csw/lib/sparcv8/ !
