grace6 broken on Sarge??

[Glen Snyder <gsnyder@rice.edu>]

The grace install works fine with Sarge, but I can't get the install of
grace6 to work. If I start with xmgrace, or gracebat, I get:
Broken or incomplete installation - read the FAQ!

I followed suggestions in the FAQ about setting the GRACE_HOME
environment....but to no avail.
I've tried  downloading the deb and using dpkg instead of apt-get....I
get the same error. 

Also, the installed size of grace6 (3408 kb) is smaller than grace (4358
kb) which it replaces. Is it possible there grace6 has dependencies, or
conflicts, which are not flagged in the install?

Thanks in advance.
