[Axiom-developer] Help with JET

[Bill Page]

Dear SPAD Gurus;

I have been working with Werner Seiler's JET package at:

http://wiki.axiom-developer.org/SandBoxJet

but on the first example I a stopped by the error message:

  Internal Error
  Unexpected error in call to system function evalSlotDomain

in:

http://wiki.axiom-developer.org/SandBoxJetFigure4

Apparently this is related to a warning in the compile of:

http://wiki.axiom-developer.org/SandBoxDifferentialEquation

Does anyone know what this message means?

Warnings:

Any help and/or suggestions would be greatly appreciated.
