Janine,
I couldn't find the "shared library" version of libskgxp either but I didn't have that error you are mentioning. When do you get that error?
From looking around in the documentation and in metalink, I couldn't find a great deal of information regarding that library, except that it's mentioned in relation to IPC (inter process communication).
Just as a side note, maybe it's related or maybe not, but I didn't install the HTTP server nor the advanced security packages when doing the package selection at installation time.
/B
