Odd.  Might be related to prelink still as I'm not sure how prelinking
affects the output of ldd.

Assuming Fedora 14, which you mentioned in your original post...

The 'prelink' cron script that normally gets run can be found in the
/etc/cron.daily/ directory.  You should be able to run it directly
with:
$ /etc/cron.daily/prelink


If that doesn't work, let's try to figure out what references the
library the hard way.  The following commands list out the names of
any libraries or executables that mention 'libnvidia-tls' (this will
take a while).
$ grep -lr 'libnvidia-tls' {,/usr,/usr/local}{/lib,/lib64}/
$ grep -lr 'libnvidia-tls' {,/usr,/usr/local}{/bin,/sbin}/
