For RedHat 9, I cannot build net-rhythmbox, because it depends on a
libFLAC.so.3 , a library that does not exist for RedHat 9.

Using these sources, as suggested by the gstreamer homepage:

# grep gst /etc/apt/sources.list
rpm     http://gstreamer.net/releases/redhat/ redhat-9-i386 deps redhat
rpm-src http://gstreamer.net/releases/redhat/ redhat-9-i386 deps redhat



For RedHat 9, I cannot build net-rhythmbox, because it depends on a
libFLAC.so.3 , a library that does not exist for RedHat 9.

# apt-get install net-rhythmbox
(*SNIP*)
The following packages have unmet dependencies:
  net-rhythmbox: Depends: libFLAC.so.3
#

net-rhythmbox should probably rely on libFLAC.so.4 , which exists for Redhat9:

# ll /usr/lib/libFLAC*
lrwxrwxrwx    1 root     root           18 May 12 10:44

The latest version of libFLAC is libFLAC.so.4 according to
http://flac.sourceforge.net/download.html and
http://rpmfind.net/linux/rpm2html/search.php?query=flac

libFLAC.so.3 cannot be found on http://flac.sf.net
