Simple emquiry....

So, I'm emerging xorg-server on my newly compiled (still bare bone) Gentoo system and it's taking fucking ages.

What the fuck is happening?

Is it compiling from source or something?

I know.

But on Ubuntu and Fedora the process doesn't take so much?!
What the heck is happening?
I even have most USE flags disabled in the make file.
Shouldn't that reduce the time by A LOT?!
