HELP WITH INSTALLING LMMS ON LINUX !!!

Having trouble with LMMS? Ask about it here.
Hi,
I wish there was an easier way to download the latest version of LMMS, but it seems the only way to do so on Linux OS is to jump through hoops of fire.

I got this far and am amazed by it, but even though, its not done -_- any help would be greatly appreciated, below is what it says when I try to use the terminal to install the sofware. i'm just so confused at this stage and have no idea what to do.

You need to install the gcc-c++ compiler.
Also you will need to install the Qt4 libraries (including devel).
What distro are you using?
Thank you for your reply, although I personally have no idea what you mean by your message. isn't there an easier way to install 0.4.13? i make music, i'm not a programmer ): is there a cd i can order or some way i can get this going easier? thank you.
You are now trying to install LMMS the hard way: by compiling it yourself...

The easy way is to install LMMS with the package manager of your distribution. Almost all will have a precompiled version of LMMS (probably not the latest version yet).
