I'm trying to run zipalign from freshly installed android sdk on Ubuntu. Although you can clearly see zipalign in proper directory, running it yields "no such file or directory". I can open it in hex editor. I can list its contents with cat, but still... no such file?!

OK, once again for anyone who happens to stumble with same problem:
sudo apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386
And it works! And to think some time ago Linux users were laughing at non-descriptive Windows error messages...
