package name mismatch

Hello! Building htk, I've got an error: TestGetPut.hs:6: Module `GetPut' is located in package `Main' but its interface file claims it is part of package `uni-events-test' It happened (as far as I got) when ghc saw in current path the *.hi file built for installation. There are some ways to work around it, but, there was a lot of such places, so can I just skip the 'package name' check and go as it is? In http://www.haskell.org/pipermail/glasgow-haskell-users/2002-January/002849.h... Simon Marlow said that it is a warning. That wold be nice, but I see an error. that's ghc-5.02 Max.
