Unable to read repository from Eclipse 3.6

Running Eclipse 3.6 and trying to get version 3.2.4 of the GWT plugin. I add the source and it results in the following:

Unable to read repository athttps://commondatastorage.googleapis.com/eclipse_toolreleases/products/gpe/release/3.2.4/3.6/content.xml. Unable to read repository athttps://commondatastorage.googleapis.com/eclipse_toolreleases/products/gpe/release/3.2.4/3.6/content.xml. com.ibm.jsse2.util.j: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is: java.security.cert.CertPathValidatorException: The certificate issued by OU=Equifax Secure Certificate Authority, O=Equifax, C=US is not trusted; internal cause is: java.security.cert.CertPathValidatorException: Certificate chaining error

I have the correct path, my local time on my machine is accurate/correct (I had read some about some odd timestamp issues with certs?), and I can't seem to find any information about this. I tried installing locally, and there are missing dependencies when I use a local archive. I am curious though, why is it trying to hit content.xml? There is no such file in the downloadable repo, and when I try to hit that URI, I get the following:

<Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message></Error>
