Syd:
I sometimes get this error message (MDK8.0, su'd to root in a terminal window):
Can you define "sometimes", please?
Is it serious and what do I do about it? Incidentally I am not trying to run perl - for example, the above is part of the output in response to the supermount command.
Maybe supermount runs perl?
To me, the problem looks like you may not have the en_GB locale set up and configured. There's some info on this in the perllocale(1p) man page. How you correct it on Mandrake, I'm not sure.
