When installing KiteModels.jl I get the warning:  
│ WARNING: could not import SpkSparseSpdBase.\_triangularsolve! into SpkSparseSpdSolver

Any idea what could be the reason?

I am not using any of these packages on purpose, they must be an indirect dependency.

On an older version of LinearSolve that includes Sparspak?

Ok, fixing this: [Fix precompilation warnings by j-fu · Pull Request #34 · PetrKryslUCSD/Sparspak.jl · GitHub](https://github.com/PetrKryslUCSD/Sparspak.jl/pull/34)

But at least this bug highlighted another problem with the old LinearSolve version…

The warning disappeared, but I do not know why.
