ok - that yields:
[17/Oct/2003:01:09:36][24062.81926][-conn2-] Debug: Data model scripts:

[17/Oct/200...
ie. $data_model_files is blank ...
checking pagages/page/sql/postgresql shows the correct files have been copied over, so i guess the package path above is correct (the /home/agiweb/openacs-4/apm-workspace/install/ part is - but i have not intercepted the install script part way)
so it looks liek apm_install_packages is never getting the files to load... just about to turn on APMDebug...
