Audacity, Ardour, Cinelerra refusing to run

[Claude Jones]

After installing the above, the programs won't run. When run from the command 
line, I get the following:

[cj at localhost ~]$ ardour
ardour: error while loading shared libraries: libsndfile.so.1: cannot open 
shared object file: No such file or directory
[cj at localhost ~]$ cinelerra
cinelerra: error while loading shared libraries: libavcodec.so.51: cannot open 
shared object file: No such file or directory
[cj at localhost ~]$ audacity
audacity: error while loading shared libraries: libmad.so.0: cannot open 
shared object file: No such file or directory
[cj at localhost ~]$

I can install those dependencies separately, but, I thought you'd want to 
know.
