My borrowed machine segfaulted while finishing building perl. So I guess 
that had nothing to do with the segfault issues. I ended up with the 
same qa.log output and same type of output on dmesg relating to libc and 
ld again.

Laptop no X on that segfaulted in the normal places

Should I try installing Ubuntu 10.04 on the borrowed machine and seeing 
if the OS works on that machine? I am still lost as nothing seems to 
really be telling me what is segfaulting. The rest of the logs basically 
look the same as the series I posted earlier.
