[R-SIG-Mac] Make check error building R 2.6.1 under OS-X 10.4.11

[Stephen Shiboski]

Trying to build R 2.6.1 on a G5 imac running OS X 10.4.11. I am using  
Xcode 2.4.1 and the gfortran (4.2.1) from r.research.att.com/tools/.  
I am using following the configuration:

./configure --with-aqua --with-blas='-framework vecLib' --with-lapack  
--with-jpeglib --with-libpng


Builds fine, but make check fails as follows:

running code in 'd-p-q-r-tests.R' ...make[3]: *** [d-p-q-r- 
tests.Rout] Error 1
make[2]: *** [test-Specific] Error 2
make[1]: *** [test-all-basics] Error 1
make: *** [check] Error 2

Here's the error:

Error: dbeta(0, 0.9, 2.2, ncp = c(0, a)) == Inf is not all TRUE
In addition: Warning message:
In dnbeta(x, shape1, shape2, ncp, log) : NaNs produced
Execution halted

I sucessfully built and checked 2.5.1 using the same set-up. The only  
thing that changed was the update to OS X 10.4.11 from 10.4.10.

It builds & checks fine on my Intel machine with the same Xcode and  
gfortran.

Any suggestions greatly appreciated. Thanks,
