[R] make check errors for R-2.3.1

[Luo Weijun]

Hello all,
I tried to build R-2.3.1 from source under Mac OS X
10.4.6. (I am doing so because only this way I can get
the 64-bit version of R)

The configure and make steps look fine. But I got
errors when I did make check-all, here is the message:

running code in 'base-Ex.R' ...make[4]: ***
[base-Ex.Rout] Error 1
make[3]: *** [test-Examples-Base] Error 2
make[2]: *** [test-Examples] Error 2
make[1]: *** [test-all-basics] Error 1
make: *** [check-all] Error 2

I am not sure what does this mean. 
One potentially related issue is that, I downloaded
and installed a gfortran compiler: GNU Fortran 95
(GCC) 4.2.0 20060512 (experimental), because we don¡¯t
have one originally. But I didn¡¯t use the latest
cctools, and our version is: Apple Computer, Inc.
version cctools-590.23.2.obj~17. Not sure whether this
matters. Our gcc compiler is:
powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple
Computer, Inc. build 5250).
Please let me know if you have any idea about it.
Thank you.
