If you do not have the Environment variable set for http_proxy, then curl will not work. This seems like your problem to me.
To see if you have http_proxy set as an environment variable, use this command:
env | grep -i http_proxy
You need to check the above variable for both your "root user" and your "local user" (local user's variables would be used if you are running yum with sudo or su root ... root user would be used if you did "su - root" or logged in directly as root.
If the result is in caps, like this:
HTTP_PROXY=http://my_username:mypassword@10.101.16.4:8080
Then curl might have an issue, so also add it in lower case like this:
http_proxy="http://my_username:mypassword@10.101.16.4:8080"
So, If you do not have a lower case "http_proxy=", then you would set it in your root's ".bash_profile" file and your local user's ".bash_profile" file. This is the line you would add to both users .bash_profile:
export http_proxy="http://my_username:mypassword@10.101.16.4:8080"
After making the change, log out and back in to have the variables take effect and then check them again with the grep command above ...
Once you have the correct lower case variable set for "http_proxy=" for both your normal local user and for root, you should be able to use yum and curl.

If the proxy server requires a username and password, add these to the URL. To include the username |yum-user| and the password |qwerty|, add these settings:
|# The Web proxy server, with the username and password for this account http_proxy="http://yum-user:qwerty@mycache.mydomain.com:3128" export http_proxy|
*Example 5. Profile Settings for a Secured Proxy Server*
[Note] The |http_proxy| Environment Variable
The |http_proxy| environment variable is also used by |curl| and other utilities. Although |yum| itself may use |http_proxy| in either upper-case or lower-case, |curl| requires the name of the variable to be in lower-case.
