www-apps/grafana-bin-4.0_beta2 seems to pull in the tar.gz archive with a name of "4.0.0-1478693311beta1" which is for the beta1 release. The correct one for beta2 seems to be named "4.0.0-1479719016beta2", based on their download page: http://grafana.org/download/4_0_0/
So upstream is very drunk, I can't get the same SRC_URI to give me the same object: !!! Fetched file: grafana-bin-4.0_beta2.tar.gz VERIFY FAILED! !!! Reason: Filesize does not match recorded size !!! Got: 41890077 !!! Expected: 41911901 Also it'll cause problems because the mirrors have a file that is named grafana-bin-4.0.0_beta2.tar.gz now
This was fixed, plus we have newer version available anyway
