Does MissingH's cabal file have a line

	Ghc-Prof-Options:       -prof -auto-all

?

The rhs of the option is added to compiler command line when the
--enable-library-profiling option is included to configure.  Without  
this,
the --enable-library-profiling switch doesn't do anything.  (Arguably a
bug that cabal silently does nothing instead of reporting an error.)

Best Wishes,
Greg
