Hi Jeff and R group,

I am having an xts specific problem with installing from R-Forge.  I was scanning the internet it looks like somebody else posted the some problem on stackoverflow yesterday and a number of people have replied but nobody has a successful solution.

http://stackoverflow.com/questions/5073154/errors-installing-rforge-version-of-xts-package-for-r

I have tried all the suggestions but continue to get the exact same error when I install xts.

For email archive reference I will re-describe it here:

After installing xts from R source forge I get a "unable to load shared object" error.  If I revert to the CRAN binaries version 7-5 it works correctly (except marginal VaR for PerformanceAnalytics in previous thread).  I've installed with the package manager, command line install.packages, and downloaded the source directly.  All have the same result.

Additionally, the file /Library/Frameworks/R.framework/Versions/2.12/Resources/library/xts/libs/i386/xts.so does exist with the following permissions:

-rwxr-xr-x  1 hward  admin  106248 Feb 17 15:28 xts.so

Any thoughts?  I will post a solution to stackoverflow when we resolve this.  Thank you.


Henry
