That info is outdated. gnucash-env has been removed and shouldn't be needed anymore. > > Long question: I am unable to successfully run example python scripts.

Probably, backend libs are not in path - but I could not > find any help regarding it. Do you have more than one gnucash installation on your system ? For example a 2.x version installed via your package manager. In any case, gnucash is supposed to search for the backend libs relatively to your python site-packages (it correctly does so on my system), but perhaps your system lays out its directories differently. Is there a directory /home/CB/bin/builds/gnucash/build-gnucash-3.7/lib/gnucash with several libraries whose names start with libgncmod ? There should be at least a libgncmod-backend-xml.so and libgncmod- backend.dbi.so.
