Yeah... confcache was an experiment that has been shelved for the time 
being.  It was designed to cache the results of various config tests 
repeated for many/most ebuilds, only dumping the cache and letting them 
retest from scratch when required (if something in the build system, say 
gcc or whatever, changed).  The problem was that a number of packages put 
bad data in the cache/database, but compiled fine themselves, thereby 
leaving the bad data to be found by the next package that tried a test 
with the same data.  Since this might be the first package after or the 
100th, it was difficult to figure out where the bad data was coming from 
in ordered to fix it.  The result was basically packages failing because 
they got a bad config, with no easy way to trace it, so they just masked 
confcache.

Advanced users can still use it if they want, using package.unmask (they 
may need to find an ebuild too, as I'm not sure whether it's still in 
portage but masked, or not even there now, but it's available in the 
archives if necessary), but they have to be prepared to manually dump the 
confcache database and try again if problems appear.  I ran it for 
awhile, but after my upgrade to dual dual-cores, decided the machine was 
fast enough at running the configs that it wasn't worth the hassle any 
more, so I turned off the feature and unmerged the confcache package.

For people who'd prefer to have portage "just work" with the least 
hassle, even if it takes a bit longer on some packages, confcache is 
definitely something you want to leave alone, at least for now.  Maybe 
someday...
