Trouble setting up mogileFS

Are you using Linux::AIO or IO::AIO?  My guess is you installed Linux::AIO
but the test suite didn't pass.  Go download it,

http://search.cpan.org/CPAN/authors/id/M/ML/MLEHMANN/Linux-AIO-1.8.tar.gz

and then:

$ perl Makefile.PL
$ make test

What does it say?

If it fails, could you also try IO::AIO and let me know what that test
suite says.  I may have to change the default preference to use IO::AIO
instead of Linux::AIO.

http://search.cpan.org/CPAN/authors/id/M/ML/MLEHMANN/IO-AIO-1.71.tar.gz

(Anybody reading this that wants to test both, I'm interested in hearing
your results....)
