-It would be nice to let some external package like GNU @code{libtool}
-handle all of this for us, but the last time we tried it,
-@code{libtool} was too slow, and didn't handle everything we need.
-So, for now, we deal with it all manually.
+From time to time users or developers suggest using GNU @code{Libtool}
+or some other mechanism to  generate shared libraries.  Experience
+with other packages suggests that Libtool tends to be difficult to
+debug and when it works incorrectly, patches are required to generated
+scripts to work around problems.  So far, the Kerberos shared library
+build mechanism, which sets a variety of makefile variables based on
+operating system type and then uses those variables in the build
+process has proven to be easier to debug and adequate to the task of
+building shared libraries for Kerberos.
