Of course nohow. But this package is not portable by desing and could be

LCL itself is by design crossplatform. And if component developers don't 
use OS and widget set functions directly the are crossplatform to. 
Widget sets (and any platform dependend code) should be isolated in 
separate packages, LCL application load widget set package at startup 
and use it. It is only impossible to switch widget sets at runtime.

So with packages Application can use ANY widget set.
