FC6: AdobeReader problem

[Gary Morain]

I recently upgraded from RC5 to FC6, and now Adobe Reader acroread is
having problems.  At first, I was having the same problem that was
being reported earlier, namely that acroread loops forever while
printing the message 'expr: syntax error'.  And so I applied the
change mentioned by Chris on 10/28/06 wherein he wrote:

> 1) Edit the file /usr/bin/acroread

> echo $mfile| sed 's/libgtk-x11-\([0-9]*\).0.so.0.\([0-9]*\)00.\([0-9]*
> \)\|\(.*\)/\1\2\3/g'

Now, acroread just exits immediately, without doing anything.

Does anyone have an idea of what is going on?  I am probably missing
some package, but I have no idea what.
