Every closer, I am now installing the 
http://mirrors.mit.edu/sage/linux/64bit/sage-7.6-Ubuntu_14.04-x86_64.tar.bz2 
version of sage, which seems like the right thing to do because my server 
is running Ubuntu_14.04, but now I run into the following error:

ImportError: libgfortran.so.3: cannot open shared object file: No such file 
or directory

I think this could be as easy as stealing the appropriate file from another 
computer and putting it into the correct location on my Travis server.
