The /MSVC switch tells the installer to NOT scan the system for a VC version to use. If you have multiple, it might pick the one you don't want.
The requirement then becomes that you run LuaRocks from within the VS commandshell, or manually call the VCVARSALL.bat batch file.

Make sure you have the Lua libraries compiled with the same compiler/runtime. Hence the link I included to LuaWinMake, which does the hard work for you. LuaWinMake can also install Lua in the proper structure for you.

The really lazy option would be to use LuaWinMulti, calling it with;

  make --51 install c:\lua

Will download lua 5.1 (or 52 or 53) sources, compile and install it in 'c:\lua`, and download and install luarocks there too.
As long as your compiler is in your system path when you call it, it will automatically use the right compiler (MS or MinGW toolchains)
