in the ebuilds it says: # FIXME: there should be a flac flag, but it doesn't work since I can't # figure out how to get libOggFLAC.so # $(cmake-utils_use_with flac Flac) i think the ebuilds shouldnt with USE flac on, no off means on. on other way, if one installed flac, and cmake check it, so we must dont use flac. but i dont understand, kdemultimedia has fixed it, but kdemultimedia-kioslaves doesnt fix it... why? fix way: uncomment $(cmake-utils_use_with flac Flac), as we cant suppose users dont install flac.

kdemultimedia-4.0.0.ebuild has fixed, but kdemultimedia-kioslaves-4.0.0 doesnt patch the file. so i suggest just patch kdemultimedia-4.0.0-flac-1.1.3.patch for kdemultimedia-kioslaves-4.0.0. and it works for me. fixed way: patch kdemultimedia-4.0.0-flac-1.1.3.patch for kdemultimedia-kioslaves-4.0.0.
