Trying to emerge --update system, system failed on python. output to StdErr indicated attempts to grep /usr/include/ tcl and tcl-tk Merging tcl & tk fixed the problem. I'm upping the severity because this happened on a relatively fresh install (completed two days ago). This is going to affect any newbie who's doing his first install and update...

Dropping sewerity back down to minor. This bug does *not* occur in systems built from stage 1, but only from systems built from stages 2 & 3. See bug 2486. "These are not the bugs you are looking for." "These aren't the bugs we're looking for." "He can go about his business." "You can go about your business."
This bug should be fixed in 2.2.1, as tcl/tk are no longer statically attached to the binary.
