[Wine] Gstreamer Help?

[SpawnHappyJake]

I have this program called ChemDraw that I use for school. It was working great yesterday in WINE 1.3.26. Then I get the bright idea to upgrade 1.3.27. Now ChemDraw doesn't work. So I'm trying to compile WINE 1.3.26 from source so that I can run ChemDraw in 1.3.26.
I get this error when trying to compile 1.3.26: 
> configure: gstreamer-0.10 base plugins 32-bit development files not found, gstreamer support disabled


I am running 64-bit Linux. I have compiled WINE from source before (for 64-bit Linux), and this 32-bit gstreamer dev stuff was not a problem. I have ia32-libs installed. I have the 64-bit version of gstreamer-0.10 base plugins installed, and the 32 bit version does not show up in Synaptic. I hunted down a deb of the 32-bit version and tried to install by double-clicking it. It says that I have the wrong architecture, and it won't let me install it. Well, duh, I know it's a 32-bit package on a 64-bit machine, install it anyways, please. But it has no over-ride option.

How important is gstreamer? And why is it being such a bear? Why can't it call the 64-bit gstreamer I have? It didn't need a special 32-bit version before, unless it was a part of ia32-libs (which if it was, it would still be there). What do I do? Any ideas?

Cheers,
Jake
