Personally, in the case of Gems, I think it's not problematic for a Gem that 
an admin has specifically installed to go in /usr/local for exactly these 
reasons.  Where I think the disagreement stems from is how to characterize 
the additional program that Gems will pull in with them.  I do not believe it 
is correct to characterize these as 'installed by the adminstrator'.  They 
were installed by the Gems system and should not be in the default path.
