how to pass to autobuild when using "apt-get -b source xxxx" ?

[Thomas Carrié <thocar@free.fr>]

Hello,

I want to install apache2 on woody, I use apache2 from backports.org but 
it seems that it doesn't include the support of shared library module 
(can't find apxs2)

So I have downloaded the deb src package apache2, I'm supposed to type 
"apt-get -b source apache2" but how do I pass the parameter --enable-so 
to the configure script ?
