We are trying to help some Bioconductor users to use these nightly builds in 64-bit mode. I noticed that when I start them with R --arch=x86_64, 'sessionInfo()' and 'version' still report i386 (this is with the latest R-2.6-branch or R-devel builds for Leopard available at http://r.research.att.com/). However, when I try to install and load a Bioconductor binary package, I do get the same error as reported by Tae-Hoon: > library(Biostrings) Error: package 'Biostrings' is not installed for 'arch=x86_64' so it seems that I'm really running R in x86_64 mode (and then the error I get with library(Biostrings) is perfectly normal since the BioC universal binaries don't support the x86_64 arch yet). Also note that when I start R with --arch=ppc, 'sessionInfo()' and 'version' report the powerpc arch. So why isn't it the case with the x86_64 arch? Thanks!
