On FreeBSD 9.0-CURRENT (amd64) I have done a

   svn co https://svn.r-project.org/R/trunk r-devel/R

and after that

   configure --without-recommended-packages

The configure script does not complain any more about missing C99 
complex support. I was able to build and install R (without recommended 
packages).

Starting R and doing examples on ?complex seems to work correct.

Thank you very much for this work. Will it exist in some way in the next 
release?
