Unless you have a _good_ build tool. Porting want ( 
http://sourceforge.net/projects/want/ ) could help.

That's why i ask. We have a large inhouse application (ERP, paper document 
processing, document managemen server), written mostly in Delphi. The ERP 
Part is build on the top of tiopf ( http://www.techinsite.com.au/ ). We have 
started porting the tiopf framework and our application but this makes no 
sense unless dynamic package loading is supported, so we have stopped our 
activities.
