 Using the HEAD version of base (Tcl 9.0.4), portindex fails on lua-* ports
 with the following messages:

 }}}

 The failure is specific to Portfiles that pull in porttest/portbuild
 namespaces via a PortGroup during the parse phase (not build) — lua-1.0 is
 the only PortGroup in the default tree that does this at parse time, which
 is why it's the sole visible symptom despite the underlying issue likely
 being in porttest.tcl/portbuild.tcl's namespace-creation logic itself.

 Reverting to commit 1555f206a (Tcl 8.6.17) solves the issue cleanly.
 Portindex doesn’t report any error any more.
