[R] help! installing R on Mac OS X 10.3.9

[Zepu Zhang]

Question 1: install R..dmg

How can I install R in ~/Applications and Rframework in ~/Library, instead of /
Library?

My preferred behavior is that if I choose /Applications for the app, framework 
goes into /Library; if I choose ~/Applications, libraries go into ~/Library (and 
don't ask me root password in this case).

Question 2: build from source

I built with this

export CC=gcc
export F77=g95
export CPPFLAGS=-Df2cFortran
./configure --with-blas="-framework vecLib" --with-lapack
make

make goes quite a long way until

...

make[3]: *** [libR.dylib] Error 1
make[2]: *** [R] Error 2
make[1]: *** [R] Error 1
make: *** [R] Error 1

By the way, a lot of 

gcc: unrecognized option '-no-cpp-precomp'

Any suggestions?

thanks.
