Thanks for the suggestion! The hash value for my download does match the one
listed on the webpage.
A further complication for R 3.0 is that a program I wrote before works fine
with R 3.0 on Mac 10.6, but gives me "Segmentation fault" error with R 3.0 on
Mac 10.8:
*** caught segfault ***
address 0x0, cause 'memory not mapped'
And the program works properly with R 2.15 on both 10.6 and 10.8.
