Added your step (4) which isn't in the instructions I'd used.

Still doesn't work on a clean system (good FPC 2.4.2, good Lazarus 
28907). Below is the last few lines of console output:

Alternatively  make LCL_PLATFORM=fpgui lcl  does appear to succeed, but 
trying to build a test project (button and label on form) fails.
