After updating from dev-lang/python-2.4.2 to dev-lang/python-2.4.3-r1 (and running python-updater), everything using python stopped working, including emerge: root@cube:~# emerge -pv portage Traceback (most recent call last): File "/usr/bin/emerge", line 12, in ? import portage File "/usr/lib/portage/pym/portage.py", line 58, in ? import getbinpkg File "/usr/lib/portage/pym/getbinpkg.py", line 8, in ? import htmllib,HTMLParser,string,formatter,sys,os,xpak,time,tempfile,base64,urllib2 ValueError: bad marshal data root@cube:~# python Python 2.4.3 (#1, Jul 2 2006, 11:22:12) [GCC 3.3.6 (Gentoo Hardened 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import string Traceback (most recent call last): File "<stdin>", line 1, in ?

Downgrading to python-2.4.2 (using python2.3 /usr/bin/emerge) fixed the problem. Upgrading to 2.4.3-r1 (and calling python-updater) didn't trigger the problem anymore, so I cannot reproduce it. :(
I'm afraid I'll have to close this NEEDINFO if it's not reproducable. If it happens again it might be interesting to move away all the .pyc and .pyo files and see if that fixes (the "marshal" data format is used to store those files).
I had same problem. When I ran emerge (no matter with or without any options) I got "bad marshal data". When I removed all .pyo and .pyc files from /usr/lib everything went back to normal. In my case the original reason of error was file system corruption.
