How can I find the build configuration for a package?

It seems like this ought to be easy...

I need to build gdal/ogr with ./configure option that isn't included in the Fedora package (--with-mdb). I want to add this on to the configuration used when the Fedora version was built. There's a utility gdal-config that shows the formats supported by the Fedora build, and I might be able to piece it together from that, but surely there's a better way!

Thanks for your time, Mack
