you could try to override the "spawn" function that gets used internally 
whenever a command action is executed. Note, that this approach will 
miss out on builders/actions that are defined as Python functions, but 
you probably don't have many of those.
Check out

   http://scons.org/wiki/LongCmdLinesOnWin32

to get an idea of how to proceed. To my knowledge there is no per 
target/source information collected by default when SCons is run. So 
you'll have to invent your own routines for tracking the times and file 
paths.

I hope this gets you started.

Best regards,

Dirk
