Yes, I did it, but this wasn't a problem :P

$ make clean all

I tried to follow the wiki instructions, and there, "Set LCL to "clean
+build" and everything else to "None" ".

With this instructions, The build finished instantly with an error I
don't remember, and can't reproduce now. Now, this, build succesfully
the LCL, but I can't get SQLDb and others pacakges.

Selecting all (but not examples) with Build&Clean, seems all goes fine,
until linking lazarus, where...:

Then how link for example the packages?

Failed to me before :P
