Sorry, I am a bit confused about your description of what happened.
Can you give us a concise timeline? (Like: Day 1 installed X. Day 3,
changed keywords to ~amd64. Day 4, tried to install texlive. Got error
message Blah.)

Which bug number?

That, uh, should not happen. How *did* you install texlive? If you
just emerged it, it should be in the WORLD set, and should not be
removed by depclean. Also, I thought the new depclean nowadays would
refuse to run if there are unresolved conflicts?

Set the correct USE flags (use 'equery uses texlive' or 'emerge
--pretend --verbose texlive' to see the complete list. Select the ones
you want/need). For example, on my box I have set in
'/etc/portage/package.use' the following

app-text/texlive dvi2tty extra games graphics humanities jadetex music omega pdfannotextractor pstricks publishers science tex4ht xetex -xindy

And then just 'emerge texlive' should do the trick.

Backing out of ~ is sometimes a non-trivial task, especially if it
involves downgrading system packages like glibc. When I had to do it
in the past, I had the luxury of time and so I 
  1) keyworded ALL currently installed version to x86 (or in your case
     amd64)
  2) changed the make.conf setting to x86 (amd64 in your case). 
This way portage won't force you to downgrade anything that is
installed and working, and after a month or two the stable keyword
should catch up or surpass the testing keyword and you'll have a
stable system again.
