The fact that many libraries are "translated from" Perl packages does not mean they are old, it means a significant part of the Lua community has used Perl before. Actually, because Lua 5.2 has been released recently and broke compatibility, libraries that support it are by definition not "old" (or at least they are maintained).
That being said, the community is small and there are indeed way too few libraries available in LuaRocks (slightly over 300). We have been discussing that on the language's mailing list and I will probably talk about it at the upcoming Lua Workshop (http://www.lua.org/wshop13.html).
