Building it manually results into nil pointer dereference on starting master

[GoogleCodeExporter]

What steps will reproduce the problem?
1. go get code.google.com/p/weed-fs/go/weed
2. go build code.google.com/p/weed-fs/go/weed
3. mkdir 1
4. ./weed server -master.port=9333 -dir=./1 -volume.port=8080

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Checkout from source and building it on the machine.
OS - Have tried the following host and target combinations
- Compile from darwin,amd64 for darwin,amd64 and run on darwin,amd64
- Compile from darwin,amd64 for linux,amd64 and run on linux,amd64
- Compile from linux,amd64 for linux,amd64 and run on linux,amd64

If you have used "-peers" option before, have you cleared the sticky
cluster configuration file? Usually it is /tmp/conf file.

/tmp/conf: No such file or directory

Please provide any additional information below.

Have tried `go build`, and also `goxc` [https://github.com/laher/goxc]
The file on the download server you provided works fine
The file which i am building does not work with new folders.
If I start a master with your compile first, and then use the existing folder 
to run my compiled version, it works

It works for me:

Maybe it's a problem with golang 1.3?

artpar, I could not reproduce this. Did you have a raft library before? Maybe 
you need to do

  go get -u github.com/goraft/raft/protobuf

to update the library.

Alright thanks. The protobuf library was the issue. There was this other issue 
which said protobuf was breaking the build because of the "Undefinds". And 
there was some other project which was broken by this issue and some said the 
temp solution was to use this

https://github.com/otoolep/raft/tree/master/protobuf 

instead of those files. so i pulled those. That worked when building but 
breaking at runtime.

Thanks.
