That sounds like a problem with Fink. Perhaps they got confused and
thought you could make Ethereal into an application bundle; we don't
provide any form of Ethereal application bundle nor do we arrange to build
one on Mac OS X.

Do
sudo find / -name ethereal -print
which, if Fink actually installed Ethereal, should tell you where it hid
the Ethereal binary.
(Note, BTW, that, as Mac OS X is a BSD with BPF support, you can just do,
just before the first time you run Ethereal after rebooting your system
sudo chown {your login name} /dev/bpf*
and then you can run Ethereal as yourself, rather than as root.)

That means that
1) somehow, the shell running in the Terminal window can find ethereal
but the shell running in the xterm window can't
and
2) DISPLAY isn't set in the terminal window.
To figure out what's going on with issue 1, what do the commands
echo $PATH
and
which ethereal
print, both in your xterm window and in your Terminal window?
To deal with issue 2, do
setenv DISPLAY :0.0
in your Terminal window if your shell is the C shell or do
DISPLAY=0.0; export DISPLAY
in your Terminal window if your shell is the Bourne shell or a compatible
shell such as the Bourne-again shell (the make your .profile or .login set
the environment variable DISPLAY, as per the above, if it's not already
set, so that you don't have to do that in any subsequently-opened Terminal
windows).
