I'd love something like this because the Lua/APR binding depends on
several external libraries that are available as Debian and Ubuntu
packages yet the best I can do right now is to list these libraries in

At the moment rockspecs can't even hint to the user how external
dependencies can be installed on their systems, e.g. a message defined
in the rockspec which is shown to the user when the install fails. Even
just that would be a big improvement :-)

If Hisham is not opposed to the idea I might look into adding support
for something like this to LuaRocks because I would consider it a big
improvement in user friendliness. Of course one can argue whether this
isn't out of scope for a Lua packages manager...
