It says "while" not "Why", the point is that in order to got installed the experimental ETS spkg I had to install wxPython before and made some changes in order to have it running (what I could attain also, and have tested satisfactorily with the wxPython demo). Then ETS spkg complain of cannot download the corresponding mayavi from the server path given and I made some changes in order to have it compiled within sage. That was all I did within a sage shell, before noticing sage complains in the way I report. > > So I tried to recompile again from the very > > beginning, but now it cannot accomplishes the task (the message in the last > > occasion was something like: configuring R with Atlas ... cannot find > > sources -src/include/Defn.h- ... r-2.10.1 /src/po/R.pot ... cannot create > > regular file 'src/src/scripts/ no such file or directory ... config.error > > cannot find sources). > > What is the *exact* error mesage? "Someting like" is not very helpful. Yes, it is not the exact error message and because I thought in that very moment I have made something wrong I did not save that particular message which is just one of the very different messages in the previous tries. > > So I download again the tar file and try again unsuccesfully. > > That is a bit pointless.

Of course I am pretty sure the md5sum is correct, but I was thinking that perhaps somebody have changed the original sage and corrected something in the distribution. > > After many > > tries I gave up and download the precompiled binary but then sending the > > ./sage command the answer to it is: > > > > r...@eolo:/opt/sage-4.3.2-linux-64bit-ubuntu_9.10-x86_64-Linux# ./sage > > ---------------------------------------------------------------------- > > | Sage Version 4.3.2, Release Date: 2010-02-06 | > > | Type notebook() for the GUI, and license() for information. | > > ---------------------------------------------------------------------- > > /opt/sage-4.3.2-linux-64bit-ubuntu_9.10-x86_64-Linux/local/bin/python: 1: > > Syntax error: word unexpected (expecting ")") > > > > Do you have any idea how can I fix this? > > You are a bit unwise running Sage as root.

I install Ubuntu 9.10, because I thought the problem of the system crash was one of incompatibilities between the upgrade and the old Ubuntu, but if you consider that the right thing would be to stay with the old Ubuntu, I am going to do that. > There have been some reports of people finding Sage binaries stops > working after they upgraded the version of gcc on their system.

Because all this is so weird to me and making me nuts, I was specting that there was another easy solution to do this, because I have invested too much time to get my stuff ready to work again, but as far as I can see I have to reinstall everything again.
