Before 2.6.25 the kernel build had never used perl, and the first perl removal 
patches were submitted for 2.6.26, so the real question is "why was it added, 
and was it worth it?"

There was a long thread on an earlier submission of the patches, which Alan 
Cox concluded (as far as I'm concerned, unless Linus, Andrew Morton, or maybe 
Al Viro want to weigh in) with this post:

  http://lkml.indiana.edu/hypermail/linux/kernel/0901.1/02108.html

Archives are linked from there, you might have to check adjacent weeks too.
