Opensource software versions by OS X distribution Have anyone or know anyone any pointer to some table, where is summarised what versions of some major opensource software was included in different OS X versions?

Like in mavericsk is perl 5.16.2 (relatively new), bash only 3.2.51 (very outdated and really wondering about yosemite version ) and such.

Exists something like distrowatch.com(Linux) for OS X too?
Apple lists all open-source files grouped by OS version on their site: http://opensource.apple.com
