I reckon here is the problem ↑
The code thinks that anything that contains a '<' is a build profile.
That's probably because it's considered rare for a Build-Depends to have
a << or a <= relation.
From that assumption on it probably just fails over itself.

Please file a bug against pbuilder, but don't expect it to be solved
quickly.

In fact, nowadays I generally recommend people use the -apt resolver,
which tends to work better in most cases, besides being faster.
