Thanks for the details... It looks like the Gnulib fsusage module is not
using the 64-bit API to get file usage data. This part should be pretty
much automatic so I'm not sure what's going on (I don't have much
knowledge in that part of the build system)...

I'm not sure if it will help but ig you have automake/autoconf you could
try the following (commands below start with the prompt character '$';
beware of line wraps...):

1. Export from SVN:
$ svn export
http://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk/
nagiosplug
$ cd nagiosplug

2. Run the autoconf/automake stuff
$ tools/setup

3. Configure and build as usual (then to test you can run the plugin
straight from plugins/check_disk).


Also, if you can manage to grab the syscalls used by df and check_disk,
I could possibly make you a patch. I'm not sure how this is done on
OS-X, but on Linux it's "strace" and on Solaris it's "truss". I.e.
$ strace df

Hope this helps...
