Yes, it does break things. It was intended only to demonstrate how big 
can be the speedup. I have mentioned I know very little about make.

That's great! And is it possible to set some default value on installation,
and make each corresponding port change it accordingly? I mean, is there a 
procedure to ensure ports do such changes?

Yes. Only, the detection can be done once per an index build.

You mean, my patch did not delete the cache at the end of the index build?
That's true. The patch was not a real one...

Totally agree on this. I tryed to make caching in bsd.subdir.mk as Kris
proposed, and I got also considerable speedup, but not as good as
with the first patch. The grep on all packages is done once per port
category. I miss how to pass the results to a child make...

Anyway, I attach the new (better, but still not fully working) patch JFYI.
