That's correct. Actually, it's probably an indirect link, because you
didn't provide -R/opt/csw/lib/$ISALIST in your linking.

If you do an ldd -v, you will get which other lib is asking for this one.
You must not link directly against those, it's the runtime linker that
chooses thet best one according to the best architecture your current
CPU supports.

That's good: OpenCSW's lib comes first, before the system's. No problem
with that, it doesn't matter if you add other -L after it.

That's good, -lz is here.

Again, it must not include it, so don't try.

What comes to my mind here is, have you installed CSWlibz-dev?
Ie, do you have /opt/csw/lib/libz.so, so that the linker can find it? If
you have only the .so.1*, it's not enough.
