downgrading Gnucash not helping

[Lenore Horner]

Because of as yet unresolved Pango problems, I need to go back to my  
previous installation of Gnucash.  I attempted to do so, but Gnucash  
complains about a symbol not existing in a dylib.  So far the only  
thing I've deactivated and reactivated the old version of is Gnucash  
itself.  Other things that successfully upgraded have the new version  
active.  Is this causing problems?  If so, how do I figure out where  
the problem is?  I attempted to use port provides to figure out where  
the "missing" dylib was coming from but as you can see below, that  
didn't look in opt/ at all.

FWIW, this is exactly the same reason that the new Gnucash 2.2.9_1  
won't run.  Gnucash actually installs and activates despite the Pango  
failure.

Any help appreciated.
