Further to this aspect of the problem, I experimented by building two very simple projects using Eric, both of which run fine in Eric and with the Python 3.5 IDLE. The first one mimics the structure of the ELFB project, which has the directory structure

MiniBrowser
	__init__.py
	minibrowser.py
	ui
		__init__.py
		mainwindow.py
		mainwindow.ui
		Ui_mainwindow.py

When I deploy it, I get the same “ImportError: No module named ‘ui’” that I reported earlier. 

make succeeded.
Running MiniBrowser...
Running '/Users/David/OpenSource/PyQtDeploy/sysroot-macosx/build/MiniBrowser.app/Contents/MacOS/MiniBrowser'
/Users/David/OpenSource/PyQtDeploy/sysroot-macosx/build/MiniBrowser.app/Contents/MacOS/MiniBrowser failed.
Traceback (most recent call last):
  File "minibrowser.py", line 2, in <module>
  File "bootstrap.py", line 969, in _find_and_load
  File "bootstrap.py", line 944, in _find_and_load_unlocked
  File "bootstrap.py", line 222, in _call_with_frames_removed
  File "bootstrap.py", line 969, in _find_and_load
  File "bootstrap.py", line 956, in _find_and_load_unlocked
ImportError: No module named 'ui'

This error seems to be triggered by the line 

	from ui.mainwindow import MainWindow 

in the minibrowser.py main script file.

The second project is flat, with no .ui module:

MiniBrowserflat
	__init__.py
	minibrowser.py
	mainwindow.py
	mainwindow.ui
	Ui_mainwindow.py

When I try to build that, I get essentially the same thing:

make succeeded.
Running MiniBrowser...
Running '/Users/David/OpenSource/PyQtDeploy/sysroot-macosx/build/MiniBrowser.app/Contents/MacOS/MiniBrowser'
/Users/David/OpenSource/PyQtDeploy/sysroot-macosx/build/MiniBrowser.app/Contents/MacOS/MiniBrowser failed.
Traceback (most recent call last):

  File "bootstrap.py", line 969, in _find_and_load
  File "bootstrap.py", line 956, in _find_and_load_unlocked
ImportError: No module named ‘mainwindow'

This seems to be caused, again, by an import command

	from mainwindow import MainWindow

in the main script file.

So whatever is going on, it’s not particular to the project I was working on. The deployed app just doesn’t seem to be able to look inside of modules.
