Got it working with a repeat attempt.

I feel like altering the ebuild to download these files first would be a good way to improve it.

Benefits:

• Parallelization / pre-downloading while deps are building (portage)
• Proper checksum support (portage)
• Failed builds do not need to re-download deps
