Which means, exactly?  Same error message?
Are you sure that you specify the file system correctly?
Is your kernel compiled with "options QUOTA"?

The sync function is optional and not necessarily required
for the rest of the module to be useful.  (Although it
_should_ work on FreeBSD.)

Of course, if the query function doesn't work either, then
there really is something wrong.

That's how I do it in a Python program.  Since I'm not
querying quotas ten times per second or so, calling the
system commands isn't really a problem.

Well, should be just three or four lines.  In my Python
program I'm doing it's the following code (this won't help
you, I'm afraid, but I'm quoting it so someone who searches
the archives might find it helpful):

quotas = dict([
    (user, qinfo.split())
        for line in getoutput("repquota -a /home").splitlines()[2:]
        for user, qinfo in [line.split(None,1)]

That creates a dictionary (Perl calls it a "hash") with
the user names as keys and their quota information as
values (a list with 9 string elements, corresponding to
the columns in repquota output).  E.g. quotas["joe"][2]
will give the soft blocks limit of user joe.  If quotas
are disabled, the dictionary is empty, so you can
simply write "if quotas: ..." or "if not quotas: ..."
to check whether quotas are enabled at all.

I'm sure you can do it similarly in Perl.
