Macromedia Flash plugin under Gentoo

Some time ago I had downloaded the Flash plugin to work with my "Mozilla-compatible" browser (Firefox), installed it just fine under /usr/lib/MozillaFirefox/ , but everytime I tried to visit a website which had any flash animation in it, the browser would just close immediately, without any warning or error message.

I quickly got pissed with that and gave up for the time being. Now I got what the (stupid) problem was: RTFM. During the installation process, the flash-installer application tells you it needs both ttfonts and urw-fonts installed. Those are fonts packages.

I did a simple

emerge urw-fonts

and that took care of one of them. But there was no ttfonts package available for installing through Gentoo's package management utility, Portage.

Searching a little I thought maybe installing the package corefonts instead of ttfonts could do the trick. And so it did. The package is masked, though, so you have to do the following in order to install it:

ACCEPT_KEYWORDS="~x86" emerge corefonts

And that's it. Now you (re)install the flash plugin under your browser's lib directory, and it should work just fine.
