[OSX]Unable to push barchart

[John Ralls]

When a one runs a graph report (e.g., Income Barchart) from the  
Gnucash app bundle, one gets a report window containing only the  
phrase "Unable to push barchart" or something similar. It works fine  
when I run gnucash from the commandline in the original installation  
tree, so I'm pretty sure that there's a library that isn't getting  
bundled. Unfortunately, I'm not able to figure out from the scheme  
source what library that might be.

Can someone give me a hint or two?
