Re: [gentoo-user] WARNING! : Newbie ahead -- EMERGEncy problems

[Robert Crawford]

If downloading time and cost are a concern, you might not get the real 
benefits of Gentoo, and maybe should consider a binary distro.

Anyway, if you wish to install stuff not in portage (almost everything is), 
you need to employ " portage overlays" you create yourself in 
/usr/local/portage- an advanced topic.

The basic Gentoo install gives you the x86 "stable" version.

The 4.x gcc versions are  "~x86", and are masked, so you need to create the 
etc/portage/package.unmask and package.keywords files to unmask anything not 
in the "x86 stable" Gentoo version.  That, or edit your /etc/make.conf file 
to go pure "~x86 testing" version. There's info on the Gentoo forum and in 
the Documentation:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#book_part3

When you need to override Portage's behaviour regarding the installation of 
software, you will end up editing files within /etc/portage. You are highly 
recommended to use files within /etc/portage and highly discouraged to 
override the behaviour through environment variables!
Within /etc/portage you can create the following files:

  a.. package.mask which lists the packages you never want Portage to 
install
  b.. package.unmask which lists the packages you want to be able to install 
even though the Gentoo developers highly discourage you from emerging them
  c.. package.keywords which lists the packages you want to be able to 
install even though the package hasn't been found suitable for your system 
or architecture (yet)
  d.. package.use which lists the USE flags you want to use for certain 
packages without having the entire system use those USE flags
More information about the /etc/portage directory and a full list of 
possible files you can create can be found in the Portage man page:
