I presume that the Linux message does not refer to DLLs? :-)

I can run example(lm.influence) and example(influence.measures) without
issue on:
R version 2.6.1 Patched (2007-11-26 r43541)
on an F8 Linux system.
I don't see anything immediately obvious in the NEWS file for 2.6.1
patched to suggest that something has changed here.
Can you provide a reproducible example here and/or try to upgrade to
patched?
I would also try to run:
R --vanilla
from the command line to provide a clean environment to be sure that
none of the other packages that you are loading are causing conflicts.
HTH,
Marc Schwartz
