[OS X TeX] Lambda Bar Symbol

[Erik Jensen]

You should have the packages and fonts you need installed already in  
any recent standard MacTeX install.

One lambdabar is part of txfonts which you can get at by putting:
\usepackage{txfonts}

just after the \documentclass line of your latex file. Then you get  
lambdabar using:
$\lambdabar$

in the text (note it is accessed in mathmode (i.e. inside the $$ or  
similar). There are a few different lambdabars in different packages  
if you want a slightly different look- you can see them in Scott's  
document you already looked at.

Regards,
Erik.
