Apache2 +openldap error

[Samuel V. Green III]

Thanks again for your help Ryan.
I agree with your suggestion that involves updating the Apache2  
portfile to include
an if/and condition.   It is my backward approach to a installing  
that caused the issue.   In the past with something
as extensive as php5,   I've ran into problems with some of the  
dependencies installing.  (By this
I mean a year ago or so.)   I've gotten into the habit of  
independently installing dependencies as
a result.  It also gives my curious mind a better view of relative  
dependencies.  Bottomline:  If I
hadn't installed apr-util independent of Apache2 I would not have had  
any problems.

Once I did get the apr-util thing sorted out,  Apache2, MySql5, and  
Php5 all built flawlessly
on a clean install of 10.4.10.
