I'm on Ubuntu 14.04 with the latest zfs installed for the PPA. Here is the history:
zpool history
History for 'mypool':
2016-05-17.21:20:56 zpool create -m none -o ashift=12 mypool raidz2 /dev/disk/by-id/ata-WDC_WD6002FFWX-68TZ4N0_K1G0YB8B /dev/disk/by-id/ata-WDC_WD6001FFWX-68Z39N0_WD-WXB1HB4MYU7M /dev/disk/by-id/ata-WDC_WD6001FFWX-68Z39N0_WD-WX11DB5140D1 /dev/disk/by-id/ata-WDC_WD6001FFWX-68Z39N0_WD-WX11DB51457V /dev/disk/by-id/ata-WDC_WD6001FFWX-68Z39N0_WD-WX11DB514Y1L /dev/disk/by-id/ata-WDC_WD6001FFWX-68Z39N0_WD-WXB1HB4TDJL4
2016-05-18.07:40:43 zpool import -N mypool
2016-05-18.11:45:12 zpool import -N mypool

The last 2 entries were created from system reboots causing the pool to be imported like this:
zpool status
pool: mypool
state: ONLINE
scan: none requested
config:

    NAME        STATE     READ WRITE CKSUM
    mypool      ONLINE       0     0     0
      raidz2-0  ONLINE       0     0     0

        sdj     ONLINE       0     0     0

I tried to use the deprecated ZPOOL_IMPORT_PATH="/dev/disk/by-id" in /etc/default/zfs but it had no effect. The zpool.cache file has references in it for the by-id drives. What can I do to ensure on reboot it imports with the by-id paths? Is it possible to manually set the import command issued automatically on reboot to import by the by-id paths?

This was fixed in the zfs-0.6.5.7 release which was tagged last week. It looks like the ppa has been updated to include these packages, can you verify the exact zfs version number.

@hippie131 can please try the following:

$ zpool export mypool
$ zpool import -d /dev/disk/by-id mypool

# Verify by-id names are used.
$ zpool status
$ reboot

# Verify by-id names are used.
$ zpool status

Is there a way to alter the command used at boot time? if there is I can just change it from "zpool import -N mypool" to "zpool import -d /dev/disk/by-id mypool"

updated to the new hardware stack and now it seems to be mounting properly with the disk IDs. Here is the kernel version I'm on now:
