Sometimes I commit things. Sometimes I have to be reminded many times before that happens. :)

global os.platform

Although "." looks like a namespace separator between "os" and "platform", that's all it is: something that looks like that. In reality, "." is just another valid character you can use in variable names. So in MacPorts there is no variable called "os". But there is a variable (an option, actually, MacPorts' special lazy-evaluated global variables) called "os.platform".

From http://wiki.tcl.tk/10259 :

"A variable name that is enclosed in braces may be composed of any characters except the right brace. When not enclosed in braces, a variable name must be composed only of letters, digits, underscore, the empty string, or namespace separators."
