However, that argument applies equally to tcl8.6.14, but the same pkgIndex.tcl works just fine on my home-built copy of that.

It's getting late and I'll have another look tomorrow and see if I can work out what's happening. In the mean time, I'd very much appreciate any help you can provide.

  Hi Alan,
 tcllib 1.21 is not Tcl9 ready.
You should try the current trunk of tcllib.
Andreas Kupries committed some more Tcl9 related changes just yesterday.
 Also note, that there is a RC0 candidate of Tcl9 (https://sourceforge.net/projects/tcl/files/Tcl/9.0.0/)

Thanks Paul - I've just spotted a reference to tcllib 2.0 on the wiki; see a message in a sibling thread.
I think I'll press on with 9.0b3 and hope to get that going happily just before 9.0 hits the streets :-). Where is the tcllib repo?
