 I thought the GLIBCXX_3.4.11 came from gcc46 but the same appears to be 
 generated when building with gcc48. The rpath should end with gcc48 if 
 you have gcc48 and not gcc46.
 
 Are you building with gcc48 by adding USE_GCC=4.8 or are you doing 
 CC=gcc48? Using USE_GCC should add the rpath setting for you.

 If opencolorio and openimageio are both built with gcc from the base 
 system you might still get the GLIBCXX linking issue through boost-libs.
 
 I'll attach a patch here to fix the gcc48 compilation which I will add 
 to the 1.1.11 update. You can either save it to 
 /usr/ports/graphics/openimageio/files/patch-ptex.imageio_ptex_PtexWriter.cpp 
 or wait for the update to be applied.
