Hi, On Windows, taking the filepath library: Building source dist for filepath-1.0... copy System\FilePath.hs to dist\src\filepath-1.0\.\System\FilePath.hs copy System\FilePath\Posix.hs to dist\src\filepath-1.0\.\System\FilePath\Posix.h s copy System\FilePath\Windows.hs to dist\src\filepath-1.0\.\System\FilePath\Windo ws.hs copy System\FilePath\Internal.hs to dist\src\filepath-1.0\System\FilePath\Intern al.hs copy Setup.hs to dist\src\filepath-1.0\Setup.hs copy filepath.cabal to dist\src\filepath-1.0\filepath.cabal D:\bin\tar.exe -C dist\src -czf dist\filepath-1.0.tar.gz filepath-1.0 D:\bin\tar.exe: Cannot use compressed or remote archives D:\bin\tar.exe: Error is not recoverable: exiting now Setup: source tarball creation failed! Tar exited with status 2 Using Cabal from about 2 minutes ago. Any idea what is wrong? Thanks Neil
