This is because kICE is built as a static library and then linked 
(copied) into a shared library.  The object files in the static library 
do not contain relocatable symbols so it is not valid to include them in 
a shared library.  We should build kICE either as its own shared library 
to be linked with DCOP or build the kICE sources into DCOP as is done 
for the windows DLL.
