 *** Exception: waitForProcess: does not exist (No child processes)
 make: *** [install] Error 1
 ---------------------------------------------------------------

 This time this looks like a clear bug:
 I know that the application program works,
 I cleared the place and applied by new
                         make configure, make build, make install,
 and it had produced this report.

 Then, I repeat  make install,  and it installs successfully.

 This is   ghc-6.6  made from source under  ghc-6.6-pre-release
 for  Linux,  i-386-type machine.
