I have "USE_XF86_4 = yes" in both /usr/share/mk/bsd.own.mk and 
/usr/src/share/mk/bsd.own.mk (they are identical, in fact).  My 
/usr/xsrc is 4.5.0, checked out this morning.  Installed userland and 
kernel are brand-new, from yesterday's sources.

However, 'build.sh -x release' on Alpha does not tar up XFree86-- only 
XdecNetBSD and XalphaNetBSD.  I thought these would not be built if one 
had the USE_XF86_4=yes directive.  What obvious thing am I missing?

(This is the first time I've actually used the build.sh script to build 
XF4, so I would expect to be ignorant about something here...)

Thanks much,
Dave
