I believe so:

I'm guessing that it's this that's causing the problems you describe  
above. You mentioned package unmasking, and this is recommended in the  
referenced forums post for those that require Real, but you might just  
try unmerging win32codecs & realcodecs & trying your update again.

I discovered this reorganisation because updating my system showed  
mplayer updating with the real USE flag being forcibly disabled, i.e.:
[ebuild     U ] media-video/mplayer-1.0_rc2_p27725-r1 [1.0_rc2_p26753- 
r1] USE="...  -radio (-real*) -rtc ... " 0 kB
Someone on #gentoo was able to help because they'd experienced the  
issue this morning.

It's not clear to me from this post whether Realplayer & these codecs  
are actually needed by mplayer in order to play .rm & .ram playlists &  
audio files. One would assume so, except for beandog's statement  
"Chances are, you don't need them anyway. The codecs are hardly used  
anymore, and most people will be fine without them."

I have been thinking recently to record Pete Tong & the other Friday /  
Saturday night Radio 1 DJs using cron & mplayer, so I can burn their  
shows to CD-R & listen to them in the car during the week. As a  
consequence later tonight I will be testing mplayer's ability to  
handle http://www.bbc.co.uk/radio1/realaudio/media/r1live.ram without  
these packages installed.
