William, thanks for this hint. But I still have a little comment.
I've just started > ./sage -f mpir-1.2.p4 and actually I really was wondering how this can work if I only have the binary version of sage. But as a surprise to me the log said... (see below)... 1) That command should be shown together with the warning message of the compiler flags. So that I can go on without having to ask on a mailing list. (I believe that at google you first have to create an account to post a message -- looks like an unnecessary burden.) 2) On the download page I would have expected to see posted a few differences of the binary and the source distribution of sage. The design with 'sage -f' and your hint of how I can recompile is great, but without asking I would certainly have downloaded the complete source distribution and recompiled from scratch. That's certainly a waste bandwidth and time. So I would suggest to add a few lines to the download pages and explaining to people for which purposes they would need the source distribution and when a binary distribution is certainly enough even for development. As for 2) maybe I haven't looked carefully enough and this information is actually there, but consider me as a person who just wants to try our sage and maybe later add a few things to sage myself. I have the choice between a source and a binary distribution. And I would certainly choose the source one, since I would think that the binary distribution doesn't let me change Sage (or at least the parts I am interested in). The source distribution is certainly not wrong, but maybe I get more than I actually need and waste bandwidth and compilation time. Do you see the dilemma? So it should be made clear that sage happily connects to a server at compile time and downloads missing sources on demand. I consider that a feature. Make it more visible.
