System: Darwin dude.terrorpin.net 8.7.1 Darwin Kernel Version 8.7.1: Wed Jun  7 
16:19:56 PDT 2006; root:xnu-792.9.72.obj~2/RELEASE_I386 i386


>Description:


textproc/html fails to build on Darwin because the pre-install step refers to 
an undefined variable TAR.


>How-To-Repeat:


When building on Darwin, I see the following error:

=> Running PRE-INSTALL script actions
/usr/bin/install -d -o root -g wheel -m 755 /Volumes/dude/pkg/share/sgml/html
cd /Volumes/dude/pkg/share/sgml/html &&   -zxf 
/Volumes/dude/pkgsrc/distfiles/html-4.01.tar.gz
/bin/sh: line 1: -zxf: command not found
*** Error code 127

Stop.
bmake: stopped in /Volumes/dude/pkgsrc/textproc/html


>Fix:


It happens to work if I add a line to Makefile with USE_TOOLS+= tar

Is this the correct fix?
