Compiling with -prof caused ghc to fail on the first import, claiming that
 the module to be imported could not be found (it worked perfectly without
 -prof).

 Initialliy I thought the -prof was just plain buggy.
 After a while I realised the real reason was that the profiling library
 package was not installed.

 The bug here is a lack of error report by the compiler. Something like
 "Profile libraries not found". Instead, the way it fails is totally
 unrelated to the cause.
