[mythtv] libmythsoundtouch compile error in 0.18.1

[Sage]

I posted this to mythtv-users, but it's looking like this is a  
question better suited for the dev list... my apologies for the  
duplication.

I'm trying to compile MythTV version 0.18.1 from source on a box  
running Debian 3.1 (stable).  I've installed the packaged lirc and  
mysql, along with associated development packages.  I've compiled QT- 
embedded and LAME from source.  I do not have X11 or DirectFB  
installed, as I am using a Hauppauge PVR-350 card for output to my  
television and therefore that should not be necessary.  I also have  
not installed ALSA -- I am trying to use OSS instead, for now.

./configure works fine, but when I do a make, the compile eventually  
exits with the following error:

If I do "./configure --extra-cxxflags=-fexceptions" then the compile  
finishes with no errors, but seeing as how there is already an  
explicit "-fno-exceptions" I figure that isn't the best way to solve  
this problem.

Can anyone tell me what's causing this error?  Am I missing a library  
or an environment variable somewhere?  I have tried installing ALSA  
as well as DirectFB but this doesn't solve the problem.  If anyone  
has any advice, it would be greatly appreciated.
