VTK has a bunch of compatibility headers to help it work with older 
compilers.  Until now every compiler has supported the old <strstream> 
header or a variation of it so there was little motivation to upgrade to 
use the new <sstream> header since old compilers don't provide it.  Some 
of our other projects use <sstream> and have a compatibility 
implementation to work with compilers that provide only <strstream>.

This can be fixed.  Please submit this as a bug report here:
