Description of problem: node-gyp-0.9.5-2.el6.noarch unresolved deps: npm(semver) < 0:2 nodejs-semver-2.0.7-1.el6.noarch is latest.
node-gyp-0.10.1-1.el6 was part of the update and has Requires: npm(semver) >= 2.0.7 npm(semver) < 2.1 Sorry, I don't get this error on my EL6 box, while I do get the others you reported.
Sorry - this really was a mistake.
