I have since debugged it some more. The configure script of autoconf-2.53 is broken, as it makes a wrong assumption about shells. As the standard FreeBSD /bin/sh does not support $LINENO, configure then tries random shells to see if they do. The first that does is "/usr/local/bin/ksh" on my system. configure then re-execs itself in ksh. This ksh does search '.' when its PATH contains an invalid element. To wit: | ice:/usr/ports/devel/autoconf>/usr/local/bin/ksh | $ cat conftest.sh | #! /bin/sh | echo got called | exit 0 | $ ls -l conftest.sh | -rwxr-xr-x 1 root wheel 36 Jul 21 20:41 conftest.sh | $ PATH=/bin | $ conftest.sh | /usr/local/bin/ksh: conftest.sh: not found | $ PATH=foobar | $ conftest.sh | got called | $ PATH=".;." | $ conftest.sh | got called This makes the Test at line 90 go wrong and configure sets PATH_SEPERATOR to ';' and later on fails trying to find programs: | checking for perl... no | configure: error: perl is not found | ===> Script "configure" failed unexpectedly. >How-To-Repeat: cd /usr/ports/shells/ksh93 make install clean cd /usr/ports/devel/autoconf make >Fix: I have sent a bug report to <bug-autoconf@gnu.org>, but I expect fixes to take quite long. A sensible workaround would be to set CONFIG_SHELL=/bin/sh in the environment of ./configure. This is also proposed by ports/39492 >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
