Fedora 15's Gnucash

[Stuart MCGraw]

Hope I can get some advice...

I have been happily using a gnucash-2.4.5 which I 
built on a fedora-11 machine for quite a while,
saving to a postgresql database.

I just upgraded the machine to Fedora 15 and 
installed a pre-built gnucash from the Fedora
packages repository.  

But when I start it up and go to "Open...", I
get a choice of only "File" or "MySQL".
Is it possible it was built without Postgresql
support?  How would I find out?
