The machine has direct connection to the internet. I downloaded pca without problem, and I can do many other downloads. I tried to run pca as root, assuming it would require file permission.
You do no need to run PCA as root, unless you actually want to install patches (--install). Otherwise I recommend to run it as a regular user.
Can you run "pca --debug" and show us the output? This will make it easier to see what's going wrong.
