Re: Re^3: What is the right value of $^O to identify Mac OS X?

The question is, how to know if I'm on Darwin or on Mac OS X using pure Perl!

The biggest difference will be only the default installation path to the R binaries.

The question is, how to know if I'm on Darwin or on Mac OS X using pure Perl! Just to re-iterate Mac OS X is Darwin, just like Redhat and Slackware are both Linux. You cannot be on a Mac OS X system and not be on Darwin. If you want to know whether your R binaries are in `/Library/Frameworks` then knowing the difference between a Mac OS X box and any other Darwin box isn't going to help you. Frameworks are a Darwin way of bundling stuff together. A non-Mac OS X box running Darwin is also likely to have R in `/Library/Frameworks`. (Equally, a Mac OS X box may not have the R binaries in `/Library/Frameworks` because whoever installed it compiled it from source and chucked it somewhere else.)	[reply] [d/l] [select]
