Yes, there is ports infrastructure that allows me to put the minimum 
required versions in the port. If you don't have a dependency installed, 
ports will install it for you. If you have the dependency, but it's too 
old, ports will tell you. :)

As I mentioned above, there is some infrastructure in ports to do this. 
In some cases, there may be multiple versions of a port (think 
lang/python2 vs. lang/python3 or www/node vs. www/node{6,8,10}) which 
allow users and other ports to choose between. And as you mention, we do 
adhere to naming and versioning conventions (specifically, semver) to 
reduce conflicts and breakage. Despite the occasional breakage here and 
there, I think it works pretty well, even with the size of the ports 
tree. :)

And thanks for the report! I will take a look at fixing all the 
www/node* ports to specify minimum required versions for all 
dependencies a little later this evening :)
