libisc, we already only use a portion of the original library. We've found and fixed bugs in the original implementation (and offered the patches to ISC), and plan to see what has changed since we last upgraded the code.
libiscis generally not installed, and when it it we usually only see the static
libisc.afile installed. Until we know for sure that the bugs we've found and fixed are fixed upstream, we're better off with the copy we are using.
libeventwas the only production version available until recently, and we've been requiring version 2 for a long time. But if the build system has at least version 2 of
libeventinstalled, we'll use the version that is installed on the system. Otherwise, we provide a copy of

liboptsis provided by GNU AutoGen, and that library and package undergoes frequent API version updates. The version of autogen used to generate the tables for the code must match the API version in
libopts. AutoGen can be ... difficult to build and install, and very few developers really need it. So we have it on our build and development machines, and we provide the specific version of the
liboptscode in the distribution to make sure that the proper API version of
