Hi Somnath,

Did Sage's suggestion fix it for you?  In my tests rocksdb wasn't building properly after an upstream commit to detect when jemalloc isn't
present:

https://github.com/facebook/rocksdb/commit/0850bc514737a64dc8ca13de8510fcad4756616a

I've submitted a fix that is now in master.  If you clean the rocksdb folder and try again with current master I believe it should work for you.

Thanks,
Mark
