Hi Junio, I noticed the revert of the 'ab/simplify-perl-makefile' branch on top of 'pu'. So, I fired up my 32-bit Linux and attempted to see if I could debug this t9001 test failure. Unfortunately, I could not get it to fail. :( Both of the 'pu' (@77e921d77d) and 'pu~1' (@cfef1ebefd) builds pass the full test-suite and, likewise, running t9001 in a loop for a count of 100 (about 45 minutes run-time each). [If it makes any difference, I don't have sendmail installed (no /usr/sbin/sendmail or /usr/lib/sendmail), or any sendmail in my $PATH.] Sorry I couldn't help with this! :( ATB, Ramsay Jones
