One way is to modify the linbox spkg and then reinstall that. If you have a source distribution, you have a file $SAGE_ROOT/spkg/standard/ linbox-1.1.6.spkg, or something like that. If you have a binary distribution, you probably need to download this from <http:// www.sagemath.org/packages/standard/linbox-1.1.6.spkg>. Run "tar jxf linbox-1.1.6.spkg" to unpack the archive, then edit the file linbox-1.1.6/src/interfaces/sage/linbox-sage.C and any other files however you want. Then you need to recreate the spkg file (make a bzipped tar file of the altered linbox-1.1.6 directory and call it something like 'linbox-1.1.6a.spkg'), and then install it: run 'sage - f linbox-1.1.6a.spkg'. You might also want to edit the file $SAGE_ROOT/devel/sage/sage/libs/ linbox/linbox.pyx, to tell Sage how to access the new pieces of linbox. Does anyone have any corrections or additions to what I wrote?
