libXext.so.6 problems in sid

[Matt <myanchys@is2.dal.ca>]

Hello, 

After a package update on my sid system the other day I suddenly started
getting errors having something to do with libc6 with many of my
programs.  Anyone else? As I'm not too familiar with this kind of
problem, I was wondering if someone could help me figure it out and
possibly fix it. Or is it specific to some bug in a sid package since I
last upgraded? 

"gpgp: relocation error: /usr/X11R6/lib/libXext.so.6: undefined symbol:
_Xglobal_lock" 

And when I ldd the libXext library I get... 

ldd /usr/X11R6/lib/libXext.so.6: 
"libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40019000) 
libc.so.6 => /lib/libc.so.6 (0x400f4000) 
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)" 

Thanks, 
Matt
