[Wine] Error with winemp3.acm for Sony ereader software

[cabernet]

I am trying to run the ereader bookstore software from Sony/Borders. It installed without any errors, but I get this error when I try to run the program:

err:module:load_builtin_dll failed to load .so lib for builtin L"winemp3.acm": libmpg123.so.0: cannot open shared object file: No such file or directory

Google did not return any useful results. I am running Debian squeeze: 
 Linux version 2.6.30-2-amd64 (Debian 2.6.30-8squeeze1) (dannf at debian.org) (gcc version 4.3.4 (Debian 4.3.4-5) ) 

and wine-1.1.37.
 
Thanks for any help you can provide!
