Of course it is. Back in 1997, this was the way it was done, and since 
1999 pkglint has required DISTNAME to be always defined. So it's no 
surprise that almost every package starts with DISTNAME and then derives 
PKGNAME from it.

I have generated some files that show how both variables are generated 
from each other:

The important thing is not the number of lines in each file, it's the 
complexity of the substitutions. Most of them are equally complicated in 
both directions. Some are simpler in one direction, some others are 
simpler in the other one.
