Although I already installed the upcoming R 2.11, I decided to build the daily snapshot from scratch, and not as a Framework version. It suffices to have a look at the configure option to see that… there are many ones! I installed many programs in my /usr/local (in line with ideas coming from Jan de Leeuw), but I never take any note of what I was doing. As a consequence, if I was to reinstall all the 18 Go of programming stuff I put in my /usr/local, it will take me one week again. Hence, I decided to now log on the main install on my Mac. Here, I used the following:

$./configure --with-aqua --with-blas='-framework vecLib' --with-lapack \ --prefix=/usr/local/R --disable-R-framework --with-readline --with-cairo \ --enable-memory-profiling --enable-R-shlib --x-includes=/usr/X11R6/include \ --x-libraries=/usr/X11R6/lib --build=x86_64-apple-darwin10 \ --host=x86_64-apple-darwin10 --target=x86_64-apple-darwin10  and the output reproduced below shows that this seems reasonable: R is now configured for x86_64-apple-darwin10 Source directory: . Installation directory: /usr/local/R Interfaces supported: X11, aqua, tcltk External libraries: readline, BLAS(vecLib), LAPACK(in blas), ICU Additional capabilities: PNG, JPEG, TIFF, NLS, cairo Options enabled: shared R library, R profiling, memory profiling, Java Recommended packages: yes  When compilation finished, I just checked that everything is ok before installing it: $ make check
$make info$ sudo make install
$sudo make install-info  Gotcha! I now have a working R 2.12. $ Rexp

I realized that yesterday I also compiled Python 3.1, this time as a Framework version. The main steps are quite simple. Download the latest build from http://www.python.org/download (Select a source tarball), then:

$./configure --enable-framework --with-universal-archs="64-bit"$ make
$make test  I ended up with some errors, like: 309 tests OK. 3 tests failed: test_ctypes test_io test_osx_env  No worry. Finally: $ sudo make frameworkinstall


The newly compiled Python 3 now sits under /Library/Frameworks/Python.framework/Versions/3.1/, and the executable is located in /usr/local/bin. I just added a symlink to get a convenient distinction between older releases (actually versions 2.5 and 2.6 which were shipped with Snow Leopard)—with default python as Python 2.6—and this one as python3:

$sudo ln -s /usr/local/bin/python3.1 /usr/local/bin/python3$ python3
