dpkg-buildpackage doesn't read debian/rules
 

I'm trying to build opensc-0.11.13, wich sources I've got with the "apt-get source opensc" command (on Debian Squeeze)
but 'dpkg-buildpackage -d -rfakeroot' doesn't get option --enable-pcsc from debian/rules
for obtaining .deb I have to manualy run ./configure ... --enable-pcsc, and after it 'dpkg-buildpackage -d -rfakeroot -nc'

Is there a way to build it with the dpkg-buildpackage only?..
