21.0.0 did not resolve the issue. Same problem - from vector_rank.cc at
lines 361-363:
```
ARROW_ASSIGN_OR_RAISE(
auto sorted, SortAndMarkDuplicate(ctx, indices_begin, indices_end,
input, order,
options.null_placement,
needs_duplicates)
.Run());
```
SortAndMarkDuplicate is a template class
```
template <typename InputType>
class SortAndMarkDuplicate : public TypeVisitor {
```
but it appears the compiler can't deduce the template parameter InputType
from the constructor arguments.
My system has never installed this program before - I get it as a dependency
for glances - either glances has changed their dependencies or it was
previously installed as a bottle, I'm not certain. In any case, something about
apache-arrow and this compiler is failing. Given that Apple Clang 12.0.0 is not
THAT old (2020) and fully supports C++17, and most of C++20 I might guess that
apache-arrow requires C++20 and that this is failing specifically due to lack
of support for class template argument deduction for alias tempaltes or
aggregates.
There may need to be explicit template parameters needed:
`SortAndMarkDuplicate<decltype(input)>(...)`
or a helper function or compilation guards to support older Apple Clang
