Install to system-wide XMMS Plugins directory simply type:
aclocal
autoconf
./configure
make
make install    - you have to do it as root or with "su -c make install"...

To install it to your user space directory ( $HOME/.xmms/Plugins ):
 ./configure --enable-user-dir
 make install

If something goes wrong please edit the Makefile, or send me a mail with the problem 
and the config.log file.
