If you have a patch, I can integrate it in the next minor release. Hopefully for the next major release we'll have freebsd builds on our side

Here's a patch that fixes compilation for me (on FreeBSD 10.1), and to my knowledge is correct, but is completely untested, since I don't use quotas. In fact, I don't even know if quotactl works on ZFS (or NFS), since it's declaration lies under <ufs/ufs/quota.h>.

Why did you set QUOTA_BYTES_PER_SPACE_UNIT to 1 though? As far as I'm
aware dqb_curblocks field is expressed in number of blocks, where one
block is DEV_BSIZE (=512) bytes.

Now, dqb_curblocks is not really mentioned in any man page I know of,
but you can infer it's intended usage by searching for it in quota(1)
sources at [1], edquota(1) at [2], or directly look at "dbtob" macro,
which is used to convert dqb_curblocks to bytes over at [3](dbtob%28x%29
is x<<DEV_BSHIFT = x*DEV_BSIZE).
