Oddly if I just install Raspbian Lite on its own and then Frotz it will
work, but install GNUstep on top and then run the same command from terminal
again (within the GUI) and again you get the "command cannot be found".

Can anyone offer pointers on where i'm going wrong please?  I am slowly
looking to build a 'retro' emulator system within GNUstep.

The difference is probably in the environment.

Assuming you’re using bash;

bash distinguishes interactive/non-interactive and login/non-login shells.

(and dynamically, starting or exiting).

    WHEN starting

     AND ( interactive AND login ) OR ( non-interactive AND --login ) )

      DO /etc/profile

         THEN    ~/.bash_profile

         OR ELSE ~/.bash_login

         OR ELSE ~/.profile

    WHEN starting

     AND interactive AND NOT login

      DO ~/.bashrc

    WHEN starting

     AND NOT interactive

      DO $BASH_ENV

    WHEN exiting

     AND login

      DO ~/.bash_logout

Terminal emulators will often start the shell in non-login mode (ie. the second case above).

Therefore they won’t load '.bash_profile' or '.profile', but '.bashrc'.

You will have to move setting of the PATH from .bash_profile (or .profile), to .bashrc

Some terminal emulators give you the option of starting the shell in login mode (--login or letting you give the command with any option you want).  But in general, it’s better to leave those shells as non-login shells, to avoid confusion and being noted as multiply logged-in the  system (cf. who -l).
