It seems the libTKernel has changed how STLport std:: namespace (through
_STDP_STD_NAME macro) gets expanded. If you have a look at libstlport5.1
symbols you should see there are defined in the stlp_std:: namespace.
Removing this #define _STDP_STD_NAME _STL from headers used by libTKernel
should fix the link failure.

I'll answer the omniORB change on the pkg-corba mailing list.
