In fact they do, probably we have tested the wrong thing:

unstable10s# dot -c
Warning: Could not load "/opt/csw/lib/graphviz/libgvplugin_lasi.so.6" - file not found
Warning: Could not load "/opt/csw/lib/graphviz/libgvplugin_lasi.so.6" - file not found

Try "ldd -r" and you see that there are lots of errors. The come from
  /opt/csw/lib/libLASi.so
because there has been no NEEDED for libCstd.so for Sun Studio in it.
Try adding -lCstd to the linker flags of liblasi and I am confident it will
work then.
