Thanks for the feedback, I agree that would be the easiest and preferable way. But which version of ming are you using that only has a makefile? The version I need (0.4.0 beta5) has a fairly involved configure script. I would have to pick out the components I need for my package and create a custom makefile for it to be easily usable (which I may end up doing, thank goodness for open source). -Cameron ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
