Should g3nd auto-detect where it's data directory lives?

Compiled g3nd following the instructions, then attempted to run it (from my home dir). Failure, as it doesn't seem to know how to look for it's data directory:

$ g3nd 
16:00:55.296763:I:G3ND:G3N Demo v0.5 starting

When launching it from the source directory which go get places it in, things work fine:

$ pwd
/home/jc/go/src/github.com/g3n/g3nd
$ g3nd
16:04:07.637331:I:G3ND:G3N Demo v0.5 starting

16:04:07.681520:I:G3ND:Xiph.Org libVorbis 1.3.3
...

Is this expected?

g3nd executable was installed in /home/jc/go/bin ?

Thanks @leonsal. That was the root cause. I use a split GOPATH with GOBIN set to the second directory. eg:

$ echo $GOPATH
/home/jc/go:/home/jc/git_repos
$ echo $GOBIN
/home/jc/git_repos/bin

Mainly to make things easy for go development. With this approach, things auto-downloaded (eg go get) are placed in $HOME/go, whereas code I'm working on is all in $HOME/git_repos. Makes backing things up easier, and keeps clear separation.

After moving g3nd from $HOME/git_repos/bin to $HOME/go/bin, g3nd finds its data directory automatically. All good. 😄
