Error installing htmlparser

[luciano de souza <luchyanus@...>]

Hello all,

I'd like to use a HTML parser. Searching on web, I found a rock called
htmlparser. As I used Lua 5.1 and htmlparser is compatible with lua
5.2, I did:

sudo apt-get purge lua5.1
sudo apt-get install lua5.2
sudo apt-get install luarocks
sudo luarocks install htmlparser

However, the result of this command was:

Missing dependences for htmlparser
lua >= 5.2
set >= 0.1

Yes, the installed version of Lua is really 5.. I don't know what
means "set >= 0.1" and I don't know what occurs.

Does someone have any idea?

I am using Lua 5.2 with ubuntu 13.10.
