cppunit linking error when compiling using argument -Dlib.type=shared

Hello,

When building a clean build of all libraries (apr, apr-util, cppunit and 
log4cxx) using the following arguments '-Ddebug=true|false -Doptimize=speed 
-Dlib.type=shared' I get linking errors when building cppunit. When removing 
the last argument (which seems to be the default ?) no problem occurs.

Could ther be a problem in the build.xml? I am not very acquainted with Ant 
(only created small build scripts once for a school project, but the complexity 
of the provided file is beyond my current capabilities).

Best regards,
Jorrit
