>Description:
Trying to build the Subversion port, while setting
WITH_MOD_DAV_SVN=yes fails.  It seems that the Makefile uses ${APXS}
to determine a build dependency, but this variable is never filled,
and this eventually causes the build to fail.  Excerpts from a build
log:

[... Mark below that it searches for an empty APXS string:]

Stop in /usr/ports/devel/subversion.

>How-To-Repeat:
cd /usr/ports/devel/subversion && make WITH_MOD_DAV_SVN=yes install
>Fix:
I'm not sure, some things seem to have changed regarding usage of
USE_APACHE and APACHE2_PORT.  The *only* place that seems to define
the APXS variable is in Mk/bsd.apache.mk, but the logic in this file
is quite unclear.  At least, I can't seem to figure out what variable
you need to set to get it to define APXS. :)

A quick hack is to put USE_APACHE=yes in the Makefile, but that gives
other problems, i.e. the produced package gets dependencies on BOTH
apache 1.3 and apache 2.0!

This might be something to coordinate with the author of
bsd.apache.mk, since I just saw that this makefile is rather new.
