The Makefile has a knob to use a specifc shell:

# Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.

Does this help ?

Otherwise: I don't know how much posix ksh88 is, it may help, if you can post some output ?

I use sometimes debug=t verbose=t ./t34XXXX.sh 2>&1 ≤ tee xx.txt but there may be better debugging utilities these days.
