mesa + libstdc++-v3

Hi,

just some time ago I experienced strange problems with gl acceleration. It 
turned out to be a problem with mesa libs being linked against different 
versions of libstdc++. I have installed libstdc++-v3 from the compat 
repository because I need to run some binary only distributed stuff. Removing 
libstdc++-v3 from /usr/libs an reemerging mesa fixed the problem. Can anyone 
reproduce this? I am not an expert of the t2 package build environment. So 
maybe someone else can fix this.

Regards,
Lars
