mogilefs newbie help

[Robert Rogers]

Hey Mark,

Here's what I get from mogstored:

debug: fd=-1; err=

Not too edifying.

Here's my environment:
Fedora3
Perl: 5.8.5
LINUX::AIO 1.3 (i tried the latest but got same error)  Fyi, in order for AIO to build i had to edit a header file. I added this line:

#include <linux/unistd.h>

so includes look like:

.... 
#include <unistd.h>
#include <fcntl.h>
#include <signal.h>
#include <sched.h>
#include <linux/unistd.h>

I got the above suggestion of your mailing list.  I think for Perlbal. Thought it was weird including the unistd.h twice although they are different files.
