A great point.  I'm not running Apple macOS 10.15 yet on the machine
I'm doing this.  So bash is there.  I looked on my 10.15 machine and
it gives a warning about "The default interactive shell is now zsh."
but does run bash 3.2.

So that's not the problem.  I figured it must be deeper into the code.

Then, using vim to look at the configure file I discovered that
it is a dos file.  I used my very handy wtch program

https://alum.mit.edu/www/toms/delila/wtch.html

to find out "what characters are in a file".  This program shows the
characters being used.  It has saved me many many times over the
years.

It confirmed that the file lines have control-M on them.

Apparently a line with just a control-M gets interepreted by bash
as a weird command that it cannot find.

I removed all control-Ms (with my 'no-m' or 'nom' script,
http://users.fred.net/tds/lab/ftp/nom)

Now the no-m copy nomconfigure runs:

% nomconfigure 
*** No flip was found
flip does not exist, has PATH been set up?
attempting to make it
nomconfigure: ./bin/make_flip: /bin/bash^M: bad interpreter: No such file or directory
*** Unable to make flip
*** No ip_pascal was found

So there are other errors.

p5c is not ready for use on macOS.
