[Rd] R-beta does not install on FreeBSD

[Rainer Hurling]

I am trying to install R-beta_2008-08-16_r46368.tar.gz on FreeBSD 
8.0-CURRENT (i386). The code stops compiling with the following message:


--------------------------------------------------------------------

This happens with all recent beta versions. R version 2.7.1 Patched 
(2008-08-10 r46284) installed and worked fine.

Could this be a bug with R-beta or is there something wrong with my 
FreeBSD version?

Any help is appreciated.

Thanks in advance,
