• I installed LUA 5.1.4 following this procedure - http://ubuntuforums.org/showthread.php?t=1874860
• I installed prosody following this command (after downloading the package) - sudo dpkg -i prosody_0.8.2-1_i386.deb

After installation, I get the following error: I have tried to use as suggested luarock and sudo apt-get install to fix these. But still it keeps showing me these errors.
