Thanks for replying Juanito and Roberts. All my extensions are in /mnt/hde2/tce; rhythmbox.tcz, rhythmbox.tcz.dep, and libsoup-gnome.tcz. I don't know how to list the contents of rhythmbox.tcz.dep.
When I open appsaudit, I was missing bzip2-lib.tcz. I downloaded it and rebooted. I open appsaudit again and was missing hwmon-2.6.29.1-tinycore.tcz. I installed the missing dependency reboot and now using appsaudit I have no missing dependencies. But, comparing the list in /tce to the list in appbrowser for rhythmbox I was missing gst-plugin-bad and gst-plugin-ugly. Gst-plugin-bad installed ok. Gst-plugin-ugly installed with error: mount: cannot setup loop device: no such file or directory. For ryhthmbox In terminal now I get: error while loading shared libraries: librhythmbox-core.so.0: cannot open shared object file or directory.
After rebooting I am getting the same error as my first post! Thanks for any help.
