libgtk3: pkg-config really required?

[Alexander Traud <pabstraud@compuserve.com>]

Two years ago, the developer tool pkg-config was added as dependency in the packages libglib-perl [1], libcairo-perl [2], and libcairo-gobject-perl [3]. Because of that, (even a minimal) Ubuntu Desktop installation contains that tool nowadays, because its Update Manager depends on libgtk3-perl.

Is that an issue, I should report as bug via the usual channels, for each of these three packages? Or was that done on some purpose, I do not understand.
