R version 0.65.0 is _not_ released: all that is available is an unstable
snapshot. This is intended for testing by developers: in particular
library ts is still under development. The banner does say

Version 0.65.0 Under development (unstable) (August 10, 1999)

to remind you.

There are no pre-compiled versions of 0.65.0 snapshots, I hope.

Thre is no usage of is.univariate.ts in the current version of the ts
library, nor in any version I am aware of. is.univariate.ts is used by the
acf function in Adrian Trapletti's tseries library. Have you by any chance
used that?  If that is not the problem, we need precise details (including
the exact day of your 0.65.0 snapshot, if recent), to R-devel please.

My guess is that you did not intend to use an unstable snapshot: the
release version is 0.64.2 and that does have RPMs for RH5.2. The release
of 0.65.0 (and the time series functions) is still about three weeks off.
