Install into /usr/local

[Richard Taubo]

Hi!

When installing some software OS X into /usr/local and reading the  
corresponding Linux manual, I see that OS X requires me to install  
using sudo whereas Linux do not.

Is there a reason for this difference, and should the OS X way cause  
security concerns?

I am e.g. thinking about as situation where you are installing  
software that has many dependencies, and is impractical to scan all  
the dependencies for the possibility of malware.


Thanks for input!


Best regards,
