> ftp.netbsd.org:/pub/NetBSD/NetBSD-1.2/sparc has the 1.2 sets for the sparc

   src/distrib/...

this directory is for building releases.

   src/domestic/...

there don't appear to be secr sets for the sparc this time.  probably
because pk isn't allow to have the code.  :-)

   src/gnu/usr.bin/send-pr/Makefile

this counts.

   src/sys/conf/newvers.sh
   src/sys/sys/param.h

these are used in building the kernel and you will note that the 
kernels are upto date.

so, the problem is that the send-pr in the sparc 1.2 release will have
1.2_BETA.  pk, perhaps you should fix this.  :-)

oh, sys/param.h may not be upto date in the installed includes.
