`waitForProcess' report in `install' in ghc-6.6

Sometimes ghc-6.6 reports this:

...

*** 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.
