I maintain the bioconductor build system and we need to use the CRAN binaries, otherwise the binary packages we produce would not be usable by most people. I understand that Snow Leopard is being phased out. However, this does mean that any package that relies on libcurl will fail on Snow Leopard (using the CRAN R binary) and so will all its reverse dependencies. Simon, do you have any thoughts on this? I know Snow Leopard is limping off into the sunset but I hope it can do so more gracefully. ;-) Dan > -pd > > -- > Peter Dalgaard, Professor, > Center for Statistics, Copenhagen Business School > Solbjerg Plads 3, 2000 Frederiksberg, Denmark > Phone: (+45)38153501 > Email: [email protected] Priv: [email protected] > > > > > > > > > _______________________________________________ R-SIG-Mac mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-mac
