I noticed the iem filters were missing from my fresh install of ubuntustudio 14.04
so I installed from synaptic
looks like a lot of the externals are missing, maybe anything that was not in iemlib folder
possibly stuff from iemlib2 iemlib3 ,etc..

also have pd 0.46 installed but had to do a sudo make install to get it into usr/local/bin
could not get the local copy in home/pd-0.46-0/ to work
make created a .libs hidden folder plus
a hidden .deps folder in /src but did not put anything in /bin
