I'm attempting to build ghc on NetBSD/amd64 by following the instructions at http://hackage.haskell.org/trac/ghc/wiki/Building/Porting, but I haven't been able to get past the configure step on the target (see errors below). Where am I going wrong here? Alternatively, any ideas on where I can find pre-built binaries for this system? NetBSD/i386 would be easy, but I've had no luck finding a 64-bit version. Here's the configure error: ./configure --enable-hc-boot --build=x86_64-unknown-netbsd --host=x86_64-unknown-netbsd --target=x86_64-unknown-netbsd checking for gfind... no checking for find... /usr/bin/find checking for sort... /usr/bin/sort checking for ghc... no checking build system type... x86_64-unknown-netbsd checking host system type... x86_64-unknown-netbsd checking target system type... x86_64-unknown-netbsd HOST: x86_64-unknown-netbsd GHC build : x86_64-unknown-netbsd GHC host : x86_64-unknown-netbsd GHC target : x86_64-unknown-netbsd configure: Building in-tree ghc-pwd ./configure[3900]: : cannot execute - Is a directory configure: error: Building ghc-pwd failed
