[R] R-2.1.0 doesn't compile on FreeBSD6-CURRENT

[Rainer Hurling]

Dear R-users,

is there anyone else with problems to get R-2.1.0 compiled on
FreeBSD6-CURRENT?

After typing '.configure' and then 'make' I get the following output:

Are there any experiences with this break?

R-2.0.1 _does_ compile on the same system.

Many thanks in advance,
