Python 2.7 on EC2
 

Hi everybody.
I have been tasked to set up an instance of Amazon's EC2 servers. Specifically, we're using the smallest Amazon Linux AMI.

After plenty time on Google, I have the machine set up more or less correctly (I think). My greatest frustration came in the form of installing Python 2.7. I installed gcc and make, and was able to install without a hickup. The guide I was (more or less) following (here) suggested I use
echo "/opt/python.2.7/lib" >> /etc/ld.so.conf.d/opt-python2.7.conf
This did not work due to me not having the right permissions, even though I also prepended the command with sudo.
In desperation, I touched the file, chmod'ed it so that I could do with it what I wanted to, and then changed it back to what it was before.

Was the chmod hack the right way to go? Will there be dire consequences in the future? ;-)
Please bear in mind that I am only very superficially familiar with Linux, and was mostly following guides.

Thanks in advance!
Regards,
JB

If you post some of the outputs from the commands you issued helps to understand what is going on.
