Problem/Bug with iwidgets package?

[Claudius Schnörr]

Hello,

when calling the insight gdb-frontend on cygwin64, it reports an error: 
"Can't find package iwidgets 4.0".
However, tcl-iwidgets-4.0.1-3 is installed.

After changing in /usr/lib/iwidgets4.0.1/iwidgets.tcl either

  * package require itcl 3.3   ->  package require itcl
    package require itk 3.3    ->  package require itk
    or
  * package require itcl 3.3   ->  package require itcl 4.0
    package require itk 3.3    ->  package require itk 4.0

this error is issued:

  * Itcl Assertion failed: "Itcl_IsClassNamespace(nsPtr)" (line 267 of
    /usr/src/ports/tcl-itcl/tcl-itcl-4.0.3-1.x86_64/src/itcl4.0.3/generic/itclResolve.c)
    Recursive internal problem.

Is this a configuration problem of the cygwin-iwidgets package, or is it 
a problem to be reported elsewhere?

Kind regards,

Claudius
