Sage-4.8 installation failed in ubuntu 10.04
First of all: information related to my computer (output of uname -a): Linux myname-desktop 2.6.32-39-generic #86-Ubuntu SMP Mon Feb 13 21:47:32 UTC 2012 i686 GNU/Linux
I was trying to install sage-4.8 from source in ubuntu 10.04. I had downloaded the sage-4.8.tar archive, created the sage-4.8 directory and then used the command "make" inside the sage-4.8 directory. After nearly two hours, I got the report (only relevant part is shown below):

Earlier I thought I probably should have used the command "sudo make" rather than "make" but later I found, in sage installation guide and also in ubuntu pages that I am allowed to use the command "make". Please suggest what I should do now. Will it be proper to use the "sudo make" command at this stage or should I do something about the already created sage-files and directories (in the failed installation process)?
