I had ever installed one component, now new a Project , so I delete
that package from palette,and remove its path from
directories/conditionals -> library path , so library path just leave
$BCB\lib;$BCB\lib\obj; ,and then compile my new Project appear "Unable
to open file Trouble.lib", I tried enable/disable each itesm from
Project -> Option ->Linker/Packages, but this problem is still exist
during linking time. The Project.bpr text is below:
How to remove that Trouble.lib forever?

I had the same problem, and the "low-level" solution to the problem is
simply to edit the *.bpr with a text editor and remove the Trouble.lib from
the LIBRARIES section.
