build broken most of the day... (libltdl?!?)

[Benjamin Reed]

The build's been broken for me since this morning with an ltdl error,
which, I can't imagine we're still using...

CMake Error: Error in cmake code at
/Users/ranger/cvs/packages/source.build/kdelibs/CMakeLists.txt:85:
ADD_SUBDIRECTORY Incorrect ADD_SUBDIRECTORY command. Directory:
libltdl does not exists.
Current CMake stack:
/Users/ranger/cvs/packages/source.build/kdelibs/CMakeLists.txt;/opt/cmake/share/CMake/Modules/CMakeCInformation.cmake;/opt/cmake/share/CMake/Modules/CMakeCXXInformation.cmake


Any ideas what's supposed to be going on?  I would have assumed
someone added that for a reason...
