[Rd] R does not compile any more on FreeBSD 8.0-CURRENT

[Rainer Hurling]

On a recent FreeBSD 8.0-CURRENT (i386) building R (any version) breaks 
with the following messages:

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

The path /usr/local/R-devel/srcunix does not exist but .../src/unix/ 
does. As a workaround I am able to do

cd src/unix
make
cd ../..
make

A second break with the same error does occur at 
/usr/local/R-devel/srcmain. Again this workaround works

cd src/main
make
cd ../..
make

Now the compilation finished without another break. What could be the 
reason for this 'path break'?  So long it seems that this error on 
FreeBSD 8.0-CURRENT only appears with R and no other third party software.

Potentially this is an error within latest FreeBSD code (?) and I have 
to ask on the FreeBSD mailing list. But before I wanted to ask on 
r-devel at . Perhaps someone here has an idea? Any hints are very welcome.

Thanks in advance,
