If you use --ltdl, it detects that LT_CONFIG_LTDL_DIR points you to use ltdl instead of libltdl as subdirectory, but it doesn't infer the --ltdl itself yet. I'm not so sure if detecting it can break anything -- after all, I may reasonably want to just update the non-ltdl files (in a different setting than CVS M4). OTOH adding more knowledge to autoreconf here seems maintenance- intensive, too. Since the order is wrong anyway: both aclocal and automake may have already traced with different macro files in place, before libtoolize is even run, it's necessary to first run libtoolize anyway. One could move libtoolize to be run before automake; but not before aclocal: eventually, libtoolize and aclocal will again compete for each installing the same macro files again, thanks to AC_CONFIG_MACRO_DIR and "aclocal --install". > Is there another libtool macro that I need to use in configure.ac to > ensure that all needed libtool files are installed at autoreconf time?

There is another bootstrapping problem, independent of the one you reported: before ltdl/m4 is populated, autom4te --trace=LT_INIT.. won't find the LT_INIT invocation, and thus will report "not using Libtool"; this doesn't happen with AC_PROG_LIBTOOL, so I wonder where we missed adding LT_INIT now..
