Problem between rmcommon and newbb

[cesagonchu]

When I install rmcommon before installing newbb, I have these two errors:
Notice: Use of undefined constant _NONE - assumed '_NONE' in file /modules/newbb/xoops_version.php line 695
Notice: Use of undefined constant _NONE - assumed '_NONE' in file /modules/newbb/xoops_version.php line 710

If I do not install rmcommon before installing newbb, I do not have those errors

Download latest newbb module from here:
