Hi,
While trying out the calculus functions on the 2.5.3 OSX build (tar.gz
package), I'm getting an error. Apparently SAGE thinks maxima isn't
installed? The file it seems to complain about below is in fact there:
osx-PowerMacintosh-Darwin/local/lib/maxima/5.12.0/binary-clisp/
lisp.run
regards
john perry
