Re: gnome-ppp & login_tty symbol on Linux

[James Henstridge <james daa com au>]

With some of the recent changes to the zvt widget, it now needs to link
with an extra library.  Edit the gnome-ppp Makefile, and where ever you
see occurences of -lzvt, add -lutil after it.

This problem has been fixed in CVS and is a known bug.

James Henstridge.
