Bugzilla Bug 145443

mt-daapd-0.2.4 will build and function for mipsel. It just needs the 
appropriate ~mips keyword in the ebuild. Tested and working on a Cobalt
RaQ2/NASRaQ not quite updated to current stable Gentoo (as of 8/28/06,
kernel-2.6.16.17). 

emerge --info (please pardon the cruft):

that's not alt, that's mips

~mips added to mt-daapd.  Thanks for testing!
