Bug#837775: ucblogo: doesn't start up without X

[Yusuke Endoh <mame@ruby-lang.org>]

Package: ucblogo
Version: 6.0+dfsg-1
Severity: normal

Dear Maintainer,

ucblogo does not start without DISPLAY environment variable.

$ logo
15:02:38: Error: Unable to initialize GTK+, is DISPLAY set properly?

I'd like to use logo in a terminal, without X.
The old version (5.5) of ucblogo actually did work.

Is this an intentional change?  Is there a way to run it in CUI mode?
