Getting the source code from the CVS repository
You can access the latest development code using a CVS client
cvs -d ':pserver:anonymous@cvs.sourceforge.net:/cvsroot/equ' login
At the CVS password: prompt just hit enter and type the following next
cvs -z3 -d ':pserver:anonymous@cvs.sourceforge.net:/cvsroot/equ' co eq-xmms
Once you have the source code in your computer you can follow the usual compilation process
cd eq-xmms && ./configure && make && su -c "make install"
If you already have done the above and just want to update your source tree do the following
cvs update -d && make && su -c "make install"
