Hi Scot,

have you also read the commit log?
- Fix leftover httpd.conf for AP_GEN_PLIST using ports.  The problem is that
  apxs does not remove module line from httpd.conf, it merely comments it out.
  Later, on Apache deinstall, the file differs from stock httpd.conf and is not
  deleted.

The issue is the following.
In case the LoadModule line is not removed from httpd.conf the port will be marked as broken by the ports build system.


I'm thinking about an parameter which change the semantic in bsd.apache.mk so the module can be installed enabled.
For example the following will do that (quick hack)

Index: bsd.apache.mk
