pkgsrc HEAD can't compile apache24

I'm confused.  How do I turn off apache-shared-modules option?  

show-options doesn't show the option.  I tried:

PKG_OPTIONS.apache24 += -apache-shared-modules

but that changes nothing.

Where did I go wrong?


# cd /usr/pkgsrc 

$ cvs update -Pd
  .
  .
  .

# (cd www/apache24 && make install)
ERROR: This package has set PKG_FAIL_REASON:
ERROR: [bsd.options.mk] The following selected options are not supported: 
apache-shared-modules.
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/www/apache24
 
 
# (cd www/apache24 && make show-options)
Any of the following general options may be selected:
        apache-mpm-event        Use multi-threaded workers in Apache web server.
        apache-mpm-prefork      Use pre-forked workers in Apache web server.
        apache-mpm-worker       Use multiple processes of multi-threaded 
workers in Apache web server.
        lua      Enable Lua support.
        suexec   Enable suEXEC support in Apache web server.

These options are enabled by default:
        apache-mpm-prefork

These options are currently enabled:
        apache-mpm-prefork suexec

You can select which build options to use by setting PKG_DEFAULT_OPTIONS
or PKG_OPTIONS.apache.


TIA,
Paul
