[Pw_forum] problem in running pwgui-5.4.0

[Muthu V]

Dear Users
I am trying to run pwgui. but it is showing the following error. i have
checked in previous forum mails and as directed by paolo i checked for itcl
and itk. everything are upto date, but still getting this error. can you
spot out where is the problem ?
i have installed itcl and itk using yum extender and their respective
version is 4.0.3 and 4.0.1. i am using fedora 23
thank you
