One option is to just copy the build directory over to the run-time location at the end of the build, i.e., as make install. This should work if you run SAGE once from the target location. Let me know when you succeed at doing this. It would be a significant step forward for SAGE. ********************************************************************************** So, I'm not sure how easy this is ... for example, when you build sage, you set SAGE_ROOT and this is used throughout the build process and the runtime usage (right? I could well be wrong). This coupling of the build time and run time environments is my biggest concern. Now, in gentoo, the builds are all done in /var/tmp/portage/ packagename/work. Then, make install is pointed to (with either -- prefix and/or DESTDIR) /var/tmp/portage/packagename/image. Under image, there might be image/usr image/share/doc image/include and so forth. For what I'm talking about using /opt for sage, we'd have image/opt/sage/<all the sage stuff>. This is done in a "sandbox" that prevents writing anywhere else in the system. So, any hardcoded paths will pose a problem (everything has to be relative to --prefix and/or DESTDIR). Finally, this gets copied into the live filesystem: for us, this would be into /opt/sage/. And this point, we have to make sure all the references in sage are relative to /opt/sage ... NOT to / var/tmp/portage/sage/image/opt/sage.
