glibc problems?

[w.steenburg at myactv.net]

After updating on Monday I get an error concerning libc.so.6.  I can only boot
into console regardless of the kernel I'm running. I get a bunch of errors whose
common part is: 

"/lib/librt.so.1: symbol __librt_multiple_threads, version GLIBC_PRIVATE not 
defined in file libc.so.6 with link time reference" 

I can't use yum, rpm or much of anything right now. That being the case, is 
there any hope or should I just wait for the test3 iso's. i could probably 
transfer some log files via my usb stick assuming mount will work if that 
helps.  If you respond to this please send me a copy to the following address
fedora at myactv.net  I won't be able to find it in the list with the one I'm
suscribed with. (I'm temporarily using webmail :(  and set this address up
special) Looking forward to any advice...
