Okay, just to chime in here... the PKG_BUILD_OPTIONS method was always 
meant to be modified to first try to lookup the PKG_OPTIONS from the 
installed package first.  It's just at the time I put the original 
PKG_BUILD_OPTIONS.* stuff in, the pkg_info on most folks' installations 
didn't support the -Q option.  I had always meant to go back and fix 
this now that pkg_info has been forced to be sufficiently new to have 
the -Q option.

So, to recap, PKG_BUILD_OPTIONS should be set by first checking for the 
existence of the package, and if it does exist, then using the result of 
"pkg_info -Q PKG_OPTIONS <pkg>", otherwise do the same dance we do now.
