I just did the following: sudo apt-get -t=experimental install autoconf
and then rebuilt the pdfresurrect as-is on my amd64 machine successfully. See attached build log. Also, looking at the build log you sent (http://qa-logs.debian.net/2020/09/26.ac270/pdfresurrect_0.21-1_unstable_ac270.log), as far as I can see, it's using autoconf 2.69c, not 2.70. Are you sure it's related to autoconf2.70? Francois -- https://fmarier.org/
