[OS X TeX] Tlmgr after migration

[Roberto Avanzi]

Hi

I just migrated to a new computer with Migration Assistant.

Now, if I issue  "sudo tlmgr --gui" from the terminal I get


Cannot load Tk, thus the GUI cannot be started!
The Perl/Tk module is not shipped with the TeX Live installation.
You have to install it to get tlmgr GUI running. See
http://tug.org/texlive/distro.html for more details.


It used to work on the other machine.

Short of reinstalling the whole of TeXLive (yikes) and
reupdating it again (yikes), what can I do to fix this?
