[Santiago Vila]

Package: src:libwww-curl-perl
Version: 4.17-3

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -B"
but it failed:

--------------------------------------------------------------------------------

It also fails here:

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

Thanks.
