Here's something else to try. I'm attaching a distribution make by 'make dist' in ~/build/nama Please untar, then: perl *PL make make test To run without install, you can put this script to in the top-level directory. #!/usr/bin/env perl use 5.10.0; use warnings; use lib "lib"; use Audio::Nama; Audio::Nama::main(); Work or not, we'll know something more.
