Help figuring out port install...(custom install)

[Jason Williams]

I was going to test installing Horde's IMP3 through the FreeBSD ports tree. 
I wanted to test it out to see if it was a viable option for our company.
Before I go on, I should mention that I installed apache and mod_ssl by 
hand before hand (For a lot of reasons really :) ).

Anyway, I navigated to the port and quickly glanced at the make file.
Everything appeared to be working well, except it could not find the apache 
install on my server:

scarydaemon# make -DWITHOUT_LDAP -DWITH_CYRUS-IMAPD install clean
===>  Installing for imp-3.2.2
===>   imp-3.2.2 depends on file: /usr/local/www/horde/turba/index.php - 
not found
===>    Verifying install for /usr/local/www/horde/turba/index.php in 
/usr/ports/mail/turba
===>  Installing for turba-1.2.1
===>   turba-1.2.1 depends on file: /usr/local/www/horde/index.php - not found
===>    Verifying install for /usr/local/www/horde/index.php in 
/usr/ports/www/horde2
===>   horde-2.2.4_1 depends on executable: pear - not found
===>    Verifying install for pear in /usr/ports/lang/php4-horde
===>   php4-horde-4.3.4_5 depends on file: /usr/local/sbin/apxs - not found
===>    Verifying install for /usr/local/sbin/apxs in /usr/ports/www/apache13
===>  Extracting for apache-1.3.29_1

It was not able to find /usr/local/sbin/apxs. But it is not located in that 
part of my system:

scarydaemon# find / -type f -name apxs -print
/usr/local/apache/bin/apxs


With that in mind, I was wondering if it is possible to some how hack the 
Makefile so it will find apxs on my system.
I've skimmed over the makefile, but have not found anything that will help 
me in figuring this out...

I thought i'd ask here, and get some help hopefully. :)

Thanks.
