[Lazarus] Adding File to Package -> Fatal: Can't find unit Controls used by ugradbtn

[dmitry boyarintsev]

You need to LCL add to the packege's dependency!

Open the package dialog (the one opened with " Package / New
Package"), press "Add" button (on the top panel of the dialog). "New
Requirement"->Package Name, select LCL. Press OK.

This will add LCL to the package requirements. You don't need to add
any directories for the LCL (if you've added you must remove them).

thanks,
