When using USE=-avi, xmms fails to build. It assumes that the file "plover-xmms127.tar.gz" exists in destfiles/ but this file is only retreived when using USE=avi. The python script fails when it doesn't find this file.
please check the -r13 (masked) ebuild.
Ben? No reponse from you this :/ Please make sure you're running the latest portage and try the -r13 (masked) ebuild of xmms with USE="-avi"...
