Not necessarily.

The 3 clause BSD license is officially a GPL compatible license.  See:

    http://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses

It is within the terms of the GPL to link GPL code to a bunch of BSD3 code
as long as you abide by both the GPL and the BSD3 license.

Hakyll would only run into trouble if it was used as a library that linked
to code which was not under a GPL compatible license.

The LGPL is still a copyleft license. Do you still have a problem
with that?

Most chunks of code can't switch license because they have dozens of
contributions from dozens of people many of whom they no longer have
contact with.
