Yes, in /usr/lib64/perl5/site_perl/5.12.2/Audio/Nama.pm
according to your error message above.

(And also the stuff in /usr/lib64/perl5/site_perl/5.12.2/Audio/Nama/)

A::E::M is an old name for the module... 

Your version is up-to-date (at least relative to CPAN).

Does Nama crash repeatedly? If so, I'm happy to have an
opportunity to understand this problem better.

I suggest you try:

$ nama -D 

This will show a lot of debug information. The last
thing you see spit out to the terminal before Nama crashes 
may be useful :-) 

Please let me know what happens!


Next, as a workaround, try installing Audio::Ecasound, the same way 
you installed Nama.

$ cpan Audio::Ecasound

You shouldn't need to know much to use the cpan client, but
of course, more knowledge helps -- sometimes just to 
make bigger, better mistakes. :-) :-)
