time to patch 

patch is in cvs now 
 
http://cvs.gentoo.org/cgi-bin/viewcvs.cgi/gentoo-x86/net-misc/icecast/files/1.3.12-errno.patch?rev=1.1&content-type=text/vnd.viewcvs-markup 

This is IceS btw, not Icecast.  IceS feeds Icecast or Icecast2

you may have said `emerge ices`, but thats not what failed ... 
when emerging the dependency icecast, the emerge failed ... even your log shows that: 
 
make[3]: Leaving directory `/var/tmp/portage/icecast-1.3.12-r1/work/icecast-1.3.12/src' 

bad me then.  my apologies.  the dependancy for ices needs to be fixed then, i
had icecast2 already installed.
