Asymptote requires a TeX/LaTeX installation; aborting now.
You can obtain the TeX distribution for Mac OS X from

caveats = <<-EOS
1) This formula links the latest version of asymptote.sty into your user
texmf directory:
~/Library/texmf/tex/asymptote-brew/asymptote.sty
This file links back to where the Asymptote source installer puts it:
/usr/local/texlive/texmf-local/tex/latex/asymptote/asymptote.sty
Other users of your machine will not be able to use the source-installed
version of asymptote.sty unless they perform a similar linking operation;
e.g.,
mkdir -p ~/Library/texmf/tex/asymptote-brew/
ln -s /usr/local/texlive/texmf-local/tex/latex/asymptote/asymptote.sty ~/Library/texmf/tex/asymptote-brew/asymptote.sty
and similarly for asycolors.sty, ocg.sty, and latexmkrc.
If you are not using MacTeX / TeX Live or you have customised your TeX
distribution, the paths shown above may not match your particular system,
but you get the idea.
2) If you wish to use xasy, run the following command to install the Python
Imaging Library (PIL):
easy_install http://effbot.org/downloads/Imaging-1.1.7.tar.gz
