Subject: Re: [PHP-DEV] [RFC] APXS LoadModule Option in configure

Oh ok, I think I see where you're getting confused.

This problem occurs when your LoadModule statement is in a *separate* .conf
file; i.e. using the "Include" statement.  APXS cannot detect this and just
sticks a LoadModule into the main .conf file.  This is what causes the
duplication.  It's a very common issue as many people (myself included)
prefer to keep their PHP configurations separate.
