I did this it turns out graphics/cairo is among them:

grep -n libz /var/db/pkg/cairo-1.4.8/+BUILD_INFO
40:REQUIRES=/usr/lib/libz.so.0
46:REQUIRES=/usr/pkg/lib/libz.so.1

I took a look at what it depends on:
( cd /usr/pkgsrc/graphics/cairo && make show-depends)
glitz>=0.5.1:../../graphics/glitz
png>=1.2.9nb2:../../graphics/png

Then I looked at their +BUILD_INFO's:
grep -n libz /var/db/pkg/glitz-0.5.6nb2/+BUILD_INFO
grep -n libz /var/db/pkg/png-1.2.18/+BUILD_INFO 
35:REQUIRES=/usr/pkg/lib/libz.so.1

So I cannot figure out why /usr/lib/libz.so.0 is being pulled in: none
of the pkgsrc dependencies requires libz.so.0. In the base libraries,
only libssh matches:

grep -n libz /usr/lib/*.so*
Binary file /usr/lib/libssh.so matches
Binary file /usr/lib/libssh.so.1 matches
Binary file /usr/lib/libssh.so.1.0 matches
Binary file /usr/lib/libz.so matches
Binary file /usr/lib/libz.so.0 matches
Binary file /usr/lib/libz.so.0.4 matches

Any suggestions on how to fix this (both libz.so.1 and libz.so.0 are
being linked against in some programs)?
