Ah, yes.  The Debian Testing package is linked against 2.2.  I should
have checked that first...

That worked wonderfully.  But I also need to be able to dynamically
replace the contents of the list.  With the old combo box, that's just
a matter of manipulating combo#list.  It isn't immediately obvious to
me how to go about doing the same on the combo w/ entry completion.
