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.
