There is no need to support multiple autotools versions, just specify in the README which ones are required. I believe that you can
well, the instructions in INSTALL.txt specify to run ./boostrap.sh :-)
(should?) also specific the required version in the configure.in and Makefile.am.
haven't found anything in the info pages ... if you know of something, please let me know ...
oh ... and btw, what's the state of libtool for osx? the last thing i heard was, that it's not gnu compatible ... since pd externals are shared objects, the optimal way to build them would be libtool, if we stick to autobuild ...
