Dear friends,

I'm pretty sure I've seen some discussion towards this subject, but 
sadly I failed to locate it. I did a clean install of TL2014 in my 
notebook and, just for fun, decided to go with -gui:

paulo at satyagraha install-tl-20140923$ sudo ./install-tl -gui

Sadly, the install aborted. Then I moved to a command line install 
(hooray!). Personally, I'm pro CLI stuff, but I was wondering why 
install-tl failed with, apparently, the Tk module. This is what yum 
tells me about the Tk module for Perl:

Sorry for a possible double post, but I was quite curious. :)

Any hints on what's going on here?

All the best,
