mozilla-1.6 4,2 Installation failure

[Robert Hamm]

Setup:  FreeBSD 5.2.1 (i386) fresh install.

Problem: The code compiles and links fine, but fails in the installation 
when it tries to cpio the files to the target directory.  The reason for 
failure is that {CPIO} is undefined and returns nothing.

Solution: Add a definition for CPIO.  It looks like it belongs in 
/usr/ports/Mk/bsd.port.mk.

I believe the same problem is true with the latest release as well.
