Right -- but then it **waits*** for input.
The input never comes, because my input is being redirected "elsewhere"
(dunno).

It's not a matter of "like" -- it's a matter of it stopping at any interactive
prompt (most have some default), and waiting for input. Then it
"pseudo-dies"-- due to hitting the timeout value in my CPAN config file.
(usually set to 15 seconds).

The rest of this seems not relevant, as I don't want interactive, but during
non-interactive build,
1) CPAN pauses at any such point to wait for input (even w/a default) until it
hits the 'inactivity timeout value.
2) Then the exit via signal is detected by CPAN as an error and no default is
taken.

It is only Makefile.PL's that prompt that have this problem.
To say that it isn't related to prompting isn't supported by the evidence.
I don't know if it would help, but maybe
the makefile.pl needs to check to see if /dev/stdin is a character device. If
it is
a pipe (which I'm guessing is the case here, as /dev/stdin isn't being read
from the /dev/tty input), then just do the default -- don't prompt.

Only when it receives input -- which it does in manual mode. But when run
automatically,
the prompting waits instead of immediately taking the default, and eventually
times out returning an error in the Makefile.PL run to CPAN.
