This error is caused by the new itk version 4, which is apparently
named as lowercased "itk" and not as traditionally capitalized "Itk".

Thank you for reporting this. You are apparently the first to report
that pwgui works with itk-4.*, after changing "package require Itk" to
"package require itk". The code has been adopted to cope with this
issue as:

if { [catch {package require Itk}] } {
    package require itk
}

This way both Itk-3.* and itk-4.* should work.

Best regards, Tone
