AqBanking Wizard not working in OS X

[Daniel Smith]

I'm having trouble getting Online Banking set up.  In my GnuCash  
2.1.5 build from MacPorts, Tools -> Online Banking Setup brings up  
the "Initial Online Banking Setup" dialog, but when I click on "Start  
AqBanking Wizard", nothing happens.  Here's the command-line output  
from my session; the dyld error appears when I click on the AqBanking  
button:

gnc.bin-Message: main: binreloc relocation support was disable at  
configure time.
Found Finance::Quote version 1.13
dyld: Symbol not found: __cg_jpeg_resync_to_restart
   Referenced from: /System/Library/Frameworks/ 
ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/ 
Versions/A/ImageIO
   Expected in: /opt/local/lib/libJPEG.dylib

I built GnuCash (r16244) via MacPorts on 2007-07-05, following the  
instructions at <http://wiki.gnucash.org/wiki/MacOSX/MacPortsDetail>,  
and using the following command:
sudo port install gnucash-devel +guile16

I've taken a look at this page:
<http://wiki.gnucash.org/wiki/Setting_up_OFXDirectConnect_in_GnuCash_2>

I assume the configuration options described there are handled  
automatically by MacPorts.

Here's a partial listing of "port installed":
   aqbanking @2.2.9_1 (active)
   gnucash-devel @2.1.5_0+guile16 (active)
   gnucash-docs @2.0.1_0 (active)
   jpeg @6b_1 (active)
   libofx @0.8.3_0 (active)

My machine is a PowerBook G4 running OS X 10.4.10.

Anyone know how I can get this to work?
