I've got "./configure" to work but I'm having a problem with FC6 in "make"
I have installed Player with success,

libtool: link: warning: library `/usr/lib/gcc/i386-redhat-linux/4.1.1/../../..//libplayercore.la' was moved.
grep: /var/tmp/player-2.0.2-fc5-root/usr/lib/libplayererror.la: No such file or directory

Here is my .bash_profile PATH=$PATH:/usr/local/bin:$HOME/bin
CPATH=/usr/local/include:$CPATH
LIBRARY_PATH=/usr/local/lib:/usr/lib:$LIBRARY_PATH
LIBDIR=/usr/local/lib:/usr/lib:$LIBDIR
LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:$LD_LIBRARY_PATH
PLAYER="/usr/local/share/player"
PKG_CONFIG_PATH="/home/lyncas/player- 2.0.3/libplayercore"
export LIBRARY_PATH LIBDIR LD_LIBRARY_PATH
export PATH CPATH LIBRARY_PATH PLAYER PKG_CONFIG_PATH
unset USERNAME

thanks for your time,
