Pkgsrc is intended to build on a wide range of NetBSD versions, as well
as Linux, Solaris and other operating systems. In practice, some
packages wont build on a particular OS or version, and where known this
is flagged in the makefiles. For example, Mozilla wont work on Motorola
68k based machines or machines running NetBSD 1.4. This can be gleaned
from the following lines in the makefiles:

   # NetBSD-*-m68k builds, but "regchrome" dumps core.
   NOT_FOR_PLATFORM=   NetBSD-1.4.*-* NetBSD-*-m68k

Attempting to build Mozilla on one of these platforms will print a
warning and exit.

If you're running -current, then a CVS checkout without specifiying a
branch will get the correct sources. To checkout the latest code for a
specific release branch you have to specify it in the initial checkout.
For instance, to get the latest kernel code from the 1.6 branch use the
following:

   cvs checkout -P -r netbsd-1-6 src/sys

A subsequent CVS update of that source will automatically pull changes
from the 1.6 branch, as this information is stored as metadata in the
source tree you checked out. In other words, you don't need to use the
"-r netbsd-1-6" when doing a CVS update.

See the following link for details:
