The difference is that these other packages don't incorporate packages 
within themselves.  With libtool 2.0, the package can choose to 
install its own libltdl and the configure script may make the decision 
automatically.  If it does so (and particularly if it replaces an 
existing libltdl), removing libltdl can cause system breakage.

Doing a 'make uninstall' for the package can unexpectedly (as far as 
the user is concerned) break the system.
