Ah, just noticed you have the following in top of the rules file which
makes my above statement redundant.

"""
#!/usr/bin/make -f
# debian/rules file for texlive-bin

export SHELL=/bin/bash
export CONFIG_SHELL=/bin/sh
"""

 * When you test manually, do you also set CONFIG_SHELL to /bin/sh?
   (Just to eliminate a source of error/difference)

Thanks,
