Problem with dyn.load in R 2.13.0

We have no details, but my wild guess would be that you did not
re-build the package for 2.13.0 and you have static libR in 2.13.0 yet
dynamic in 2.12.2.

Per my prior note, my guess at the root of the issue is use of user
libraries, which is common here.

Here are futher details if that helps.

 R2.13 was downloaded and built this AM in my ~/temp directory, using
the standard 
  ./configure
  make
Then a copy of the shell script was copied to in ~therneau/bin/R13 for
my convenience.  I paid very little attention to the output of
configure.

This is running on a shared server using CentOS release 5.5 (98 users at
the moment).
R2.12.2 is centrally available.

I can't find a libR.so anywhere -- perhaps it's static.

Thanks for everyone's help.
