Hi all,
Some good news. :)

I found what's been going wrong. It was sudo. Using sudo instead of su
- to nixos-rebuild switch is what causes problems.
So I was able get git svn and all is well. :)
I used /nix/etc/config.nix containing :

{
   git = { svnSupport = true; };
   subversion = { perlBindings = true; };
}

su -
nixos-rebuild switch

All went well and I can now do git svn in a konsole.

So thanks to everyone that helped, I really needed to get git svn. It
was actually after reading Marc's message that it dawned on me to try
su - instead.

This does however beg the question, does my user account need to be in
the nix group or similar to be able to issue sudo nixos-rebuild switch
and avoid problems like this?

Anyway, thanks all for taking time out to reply during your busy day,
it is greatly appreciated.

Regards,
Tony
