installation of R (14.1 and 15.1) fails: [reg-packages.Rout] Error 1

Hello,

I'm trying to install R on two Linux machines:

1.

uname -a

Linux cs-wsok 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26 09:36:26 UTC
2012 (641c197) x86_64 x86_64 x86_64 GNU/Linux
2.

uname -a

Linux csltok.swansea.ac.uk 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26
09:36:26 UTC 2012 (641c197) x86_64 x86_64 x86_64 GNU/Linux

I am trying version 14.1 on first machine and 15.1 on second machine.
On both machines I get the same test error:

1.
  comparing 'reg-tests-2.Rout' to './reg-tests-2.Rout.save' ... OK
  running code in 'reg-examples1.R' ... OK
  running code in 'reg-examples2.R' ... OK

I looked at
http://www.stats.bris.ac.uk/R/doc/FAQ/R-FAQ.html#R-Bugs
and didn't find specific suggestions about information to provide in
case of building errors. And I don't know how to get more information
about these test-errors.

Hope somebody can help.

Best regards

Oliver
