Here is the g++ command I made by hand.
g++ testrender.cpp -I/Users/kunigami/dev/osl/dist/macosx/include/OSL/
-I/opt/local/include -I/Users/kunigami/dev/oiio/dist/macosx/include/
-lOpenImageIO -L/Users/kunigami/dev/oiio/dist/macosx/lib
-L/Users/kunigami/dev/osl/dist/macosx/lib/ -loslexec -loslcomp -loslquery

It's actually the complete error message. I've compiled in verbose mode for
more information, but I don't think they're useful at all:
http://paste.ubuntu.com/615807/
Here's the output of the cmake execution for the working case:
http://paste.ubuntu.com/616027/
It seems that OSL_NAMESPACE is not being set by the compiler.
I made the following test on testrender.cpp:
cout << OSL_NAMESPACE << endl;
But the compiler said that OSL_NAMESPACE was not defined.
I've also listed the dynamic libraries linked to executable ./testerender
(from the working version)

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
Nope - It's vRanger. Get your free trial download today.
