At least the following packages suffer from this problem: bindings-common bindings-libusb bindings-posix
Most .tar files contain entries for the directories that precede the entries for the files. This is only by convention however. It looks like this tar file has an entry for "src/Bindings/SomeFile.hs" without any preceding entries for "src/AnotherFile" or for the directory itself "src/Bindings/".
Thanks for the tip. I used Mercurial archive to create those tars: hg archive -t tgz -p 'bindings-common-1.1' ~/bindings-common-1.1.tar.gz I'll check if this is known in Mercurial, specially the weird output got from 7zip. Meanwhile, I'll be uploading as soon as possible new versions of those packages with runhaskell Setup.hs sdist Best, Maurício
