Hi, All; I've compiled and installed successfully "presumably" 64-bit R on Leopard. But when I tried to run R, I got the following error: /usr/bin/R: line 179: /Library/Frameworks/R.framework/Resources/etc/ i386/ldpaths: No such file or directory Here is the configuration I used: CONFIG_SHELL=/bin/bash ../R-devel/configure r_arch=x86_64 LDFLAGS="-L/ usr/local/lib64 -L/usr/X11R6/lib" CC='gcc-4.2 -g -O3' CXX='g++-4.2 -g - O3' F77='gfortran -g -O3' FC='gfortran -g -O3' --with-blas='-framework vecLib' --with-lapack Thanks in advance Tae-Hoon Chung
