Getting TensorFlow.jl to build properly

extractcerts.jl

I was getting the following errors when running 
Pkg.update("TensorFlow") 
On my ubunutu 14.04

INFO: Building TensorFlow.jl for CPU use only. To enable the GPU, set the TF_USE_GPU environment variable to 1 and rebuild TensorFlow.jl

curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
