The configure script of the devel/autoconf port prefers a variety
of third-party shells (e.g. bash) over /bin/sh to run itself. The
same shell as used for configuration is inserted into the #! path
of the generated "autoconf" script.
In other words, if bash is available on a system when the devel/autoconf
port is built, the installed autoconf script will look like this:
# -*- shell-script -*-
# autoconf -- create `configure' using m4 macros
In order to remove this hidden dependency and make the build
deterministic, I suggest to force CONFIG_SHELL=/bin/sh.
