Hi,
Looks like the php-* PECL packages are getting their debian/control
generated at build time from a debian/control.in.
If you didn't know, this is *NOT* policy compliant. The policy clearly
says source packages must have a not-generated debian/control in good
shape (though I haven't taken the time to find where this is written in
the policy, I just know it's forbidden...). Please stop doing this.
If you still need to generate it, then you can have a look how the Linux
kernel package does it. They generate the debian/control from control.in
thanks to some internal tooling, but save the debian/control in the
generated form in their source package. That may be a nice workaround,
and the better way to go for you.
Cheers,
