Not able to install the couchnode library from npm - seems to be a node.gyp issue

I am having trouble installing couchbase module from npm. I see permission issues in the npm console log even if i am doing "sudo install couchbase". I did install libcouchbase via brew and did not get error messages (I think). I have installed multiple other npm modules (some with c-code with no issues).

Please let me know if this is not the correct channel to post issues like this one (I just thought as the module was so young all feedback is good). Also, at this time this stops me from piloting couchbase

I have attached the npm error log
