Thanks for following up.

Ah, I see the problem.
You needn't tell Autotools that you have a preferred shell to the one it looks
for by itself (and actually, if you just let configure run with whatever shell
it can get, it might even find and choose /usr/local/bin/bash provided that you
have /usr/local/bin in your command search PATH, and provided that there is not
a shell called 'sh' also somewhere in PATH that provides all the features
Autotools is looking for.
as_save_IFS=$IFS; IFS=$PATH_SEPARATOR
for as_dir in /bin$PATH_SEPARATOR/usr/bin$PATH_SEPARATOR$PATH
do
IFS=$as_save_IFS
test -z "$as_dir" && as_dir=.
case $as_dir in
/*)
for as_base in sh bash ksh sh5; do
as_candidate_shells="$as_candidate_shells $as_dir/$as_base"
done;;
esac
done
IFS=$as_save_IFS
Generally, bash is an excellent shell to use interactively, but it is a little
buggy and considerably slower than some of the cut down shells such as
Debian's /bin/sh which is a link to the lightning fast Almqvist shell. Unless
you are experiencing real problems with the shell that configure selects for
you, then you probably shouldn't need to force another shell.
However, you can safely force an alternative shell to execute the various
Autotools scripts by setting both SHELL and CONFIG_SHELL, like so:
./configure SHELL=/usr/local/bin/bash CONFIG_SHELL=/usr/local/bin/bash
<other arguments as usual>
That should ensure that SHELL is then set correctly in libtool and Makefile to
match the tests that configure ran earlier.
Cheers,
