Hi all, If I run: scons fullclean scons ghc=/usr/bin/ghc-6.4.1 It compiles for a while and uses the correct version of ghc, until it gets to this part: Getting dependencies for src/compiler98/Compile.lhs. Then I get an error: An error ocurred running `ghc -M-optdep-f-optdepsrc/compiler98/.Compile.lhs.dep -fwarn-missing-signatures -i./src/compiler98:./src/libraries/general:. /src/libraries/core:depends/cpphs:depends/filepath:./src/interactive src/compiler98/Compile.lhs`: ./src/compiler98/ByteCode/Write.hs:9:7: Could not find module `Control.Monad.State': Use -v to see a list of the files searched for. I think the problem is that it is using "ghc" to generate the dependencies, when it ought to be using "/usr/bin/ghc-6.4.1" Cheers, Bernie
