In a related question, I asked about getting a blackboard bold 0 in addition to a 1. But now I'd like to do it along with \usepackage[utopia]{mathdesign}. If I try to \usepackage{bbold}, I get the error
Latex Error: /usr/local/texlive/2011/texmf-dist/tex/latex/bbold/bbold.sty:42 LaTeX Error: Command `\mathbb' already defined.
It seems that \usepackage{dsmath} works with \mathds{01}, but if possible I'd like to use them with the command \mathbb. Is there a way to make that work?
\let\mathbb\relaxbefore\usepackage{bbold}, which should go after the call tomathdesign. However consider that this font is rather visually incompatible with Utopia. – egreg Feb 26 '12 at 20:38
