Ubuntu :: Download All Development Libraries At Once?

It seems to me that if I could download every single development library or dependency available for Linux/Ubuntu, that it would make my life a whole lot easier as for as acquiring software. All I would have to do then is run configure/make/make install which isn't that bad.

The problem being here that the repositories in Ubuntu suck. In fact, they suck in all Linux distributions. The only things they are good for is gathering dependencies needed to compile programs. All the packages that I actually want are frozen and therefore are outdated and useless. I've had to learn how to compile stuff just so I could get the programs working like they do in Windows. Except in Windows all I had to do was double click on the file and not spend hours figuring out what to do.

Then of course there is the other problem that about 90% of the software I need is not included in these repositories.

Have Linux people not heard of the Internet? The ultimate repository? It sure works well in Windows.

Anyway, if there is a way to download all these files in one go (because let's face it, I'll have them all downloaded eventually) I would like to know how. Even if they take up 100's of gigs it would be worth it for the savings in time and energy.
