Julia - Language - Handling Package Build Errors

Today while trying to install and Build Rmath package in Julia, I was receiving the following error:

julia> Pkg.build("Rmath")

On investigating, I found that the root cause of the error was the line marked in red above. Hence, I searched for the error in google. I found the following stackoverlow answer helpful:

https://stackoverflow.com/questions/3160909/how-do-i-deal-with-certificates-using-curl-while-trying-to-access-an-https-url/31424970#31424970

So, I followed the instructions in it and created the following file with content in my home directory. 

~ $ vi .curlrc
~ $ more .curlrc 
cacert=/etc/ssl/certs/ca-certificates.crt
~ $ 

This was done to inform curl about the location of certificates in Ubuntu 14.04

After this, I ran the build command in Julia again:
