Well TCSH is now in the repository so I installed that, then tried to install the brother propriety drivers, but I hit another snag, the version of TCSH in the repository is version 6.14 which has a known bug with a color variable, this has been fixed in later versions of TCSH the current version is 6.17.
But the present repository version will not let me run my proprietary install script to unpack a rpm as it breaks when it comes to the color variable bug.
I don't expect my Brother driver to ever be included with any Linux distro.
Will wait a few days to see if the current TCSH appears in the repository, if not I will have to manually insert the current version myself but I really don't want to do that and maybe upset synaptic.
