I am trying to install labdsv from CRAN binaries (or source) to use with R 2.3.0 from Mac OS X, but the package fails to install properly. Here is the message that I receive from R when I type library(labdsv): Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/labdsv/libs/ppc/labdsv.so': dlopen(/Library/Frameworks/R.framework/Resources/library/labdsv/ libs/ppc/labdsv.so, 6): Library not loaded: libR.dylib Referenced from: /Library/Frameworks/R.framework/Resources/library/ labdsv/libs/ppc/labdsv.so Reason: image not found In addition: Warning message: cannot create HTML package index in: make.packages.html() Error in library(labdsv) : .First.lib failed for 'labdsv' mgcv, MASS, and akima load properly. If I try to install using CRAN source the process ends with: chmod: /Library/Frameworks/R.framework/Versions/2.3/Resources/library/ R.css: Operation not permitted Thanks in advance for any help.
