[mythtv-users] 0.18.1 on x86_64 and lirc not working

Just an update on my progress:

I was finally able to get a clean build after doing ./configure -- 
disable-firewire and --disable-xvmc - somehow it wasn't finding  
either of those even though they were installed (remember I had a  
completely working myth system with atrpms before) - but when I  
installed it and rebooted the frontend spit out "your version was  
compiled with libmyth xxxx while this version is xxxx. You'll have to  
recompile everything and do a make distclean" (or something similar).  
Ok. I recompiled and did a distclean before building and the same  
thing happened.

I then finally decided to restore everything back to where it was - I  
removed and reinstalled mythtv from atrpms and now I'm back to where  
I started with no myth lirc working ;)

I've thought about upgrading to CVS  - is there a way to know if the  
lirc bug has been fixed?
