I am a little new to gentoo, and have done something stupid apparently, like emerging app-emulation/emul-linux-x86-glibc and some others in that directory. Consequently, emerge always fails with this message:

* It appears you have switched to the 2005.0 profile without following
* the upgrade guide. Please see the following URL for more information:
* http://www.gentoo.org/proj/en/base/a...rade-amd64.xml

I get the same message whenever I try to remove a package.

Some programs are also now experiencing a failure to load OpenGL libraries.

Here is the complete output of emerge --info, if that provides anything relevant to anyone else.

Any help at all would be appreciated. Any halfassed solution to make emerge work again would be appreciated. I finished this stage one installation about two weeks ago, and I do not want to do that again.

I don't have a 64 bit system myself, but according to the gentoo documentation you need the "multilib" USE variable to be able to compile 32bit and 64bit binaries. Maybe that's all? I'm not sure. Maybe someone with 64bit experience has a better answer.

This is really wierd. Multilib is declared in /etc/make.conf:

USE="multilib qt kde alsa nvidia X aim cdr..."

Yet it does not appear in emerge --info.

Setting multilab as a use flag on the command line with emerge makes no difference.

You could also try the Gentoo forums, unless you've allready tried that of course.

Yeah, I know, but I never get responses at that forum. I tried gentoo six months ago and wiped my hard drive after just two weeks because I could never get the sound to work, there was some driver going crazy and hogging my processor, and I could get no support whatsoever. This time however, I ended up with a perfect and beautiful installation, and managed to screw it up myself by playing around with masked packages.

I have just moved, and do not have internet at my apartment for the next week so I am at the campus library and cannot be exact here, but I have half-assed the immediate problem. I found the error message from my initial post in /usr/portage/../profile, and simply commented it out along with the preceding condition. Emerge now works as it should for the most part...gimp compiled successfully, though I did occasionally get error messages on other packages. I did not have time to test this extensively before I had to leave my internet connection. The condition I commented out was something like

if [/usr/lib32 -L -o /lib32], (I invoke my previous disclaimer about not being exact).

The problem I have now is that even though anything compiled from source works fine, all 32 bit binaries I have installed both before and after this problem arose and I halfway fixed it, do not work, and fail on errors that they cannot find libraries. In my root directory, I have lib, lib64, and lib32 directories. "lib" is currently a sym link to lib64. I also however have a /emul/.../lib32. /usr/lib32 was a symlink to this directory. I was under the impression that the condition above might be checking to see if it points to /lib32 instead. Changing the link however makes no difference. How are my 32-bit libraries supposed to be set up, and/or is there a config file or variable that I can set to take care of this. I am not sure how specific this question is to Gentoo (I know that 64 bit SuSE did not have a directory structure like this), and it may be more appropriate for the Gentoo forum, but hey, I like you guys better.

The actual condition that the script checks prior to the error message is

if [ -L /lib32 -o -L /usr/lib32 ] && [ ${PORTAGE_CALLER} != "repoman" ] ;.
