in reply to Writing a negative regex using =~

If I understand your problem correctly, you need a negative look-ahead:

/^(?!.*(?:GBFER|GBFOO))/

However I suggest redesigning your system so that it does not prevent you from using !~.

    Heh, given the amount of time I've spent on the regex, that would be the better option!
