[Lazarus] Why does Lazarus insist on rebuilding the LCL?

I'm not sure I understand you on this.
What should I delete?

I used to be able to do a "build (clean) lcl" from within the IDE, now
I cannot anymore.
I made changes to maskedit.pp (for debugging purposes) and wanted to
rebuild the LCL, but after selecting the buildprofile LCL and pressing
Build, nothing happend.
When I rebuilt the application, it also did not rebuild the LCL.

Obviously I'm missing something here...

So, what now?
