Using an ' idjc ' compiled without flac :
.. You will get the above errors ..
# yum install \
pygobject2-devel pygtk2-devel python-mutagen
flac-devel \
jack-audio-connection-kit-devel libsamplerate-devel \
libsndfile-devel speex-devel
And if you wish : ffmpeg-devel libmad-devel
.. from
http://rpmfusion.org/Configuration
cd idjc-0.8.1/
./configure && make , # make install
I had to deactivate selinux to start idjc / jackd :
# system-config-selinux .
I used this source + the patches ( may not be nessecary )
